         [0005]    U.S. Pat. No. 4,637,631 (Jan. 20, 1987, Baer) and U.S. Pat. No. 4,743,047 (May 10, 1988, Baer), which is a continuation-in-part of Baer U.S. Pat. No. 4,637,631, together disclose a book in combination with a mirror. A book such as one might ordinarily keep on one&#39;s shelf has a mirror embedded in one of the bound sections such that upon picking up the book and leafing through several pages, one is confronted with one&#39;s reflection. This allows for an added dimension to communication. The mirror is embedded in a thick section, the leaves of which may be bound and laminated together, a hole corresponding in dimensions to the mirror is cut partially therethrough, a mirror is immovably placed in said hole. In one embodiment, the mirror is mounted in countersunk fashion in the back cover with mounting means. In another embodiment, a reflective surface of the mirror is flush with the inner surface of the cover. In another embodiment, the mirror is embedded into a rather thick page wherein is embedded a mirror that would reflect the reader&#39;s face when the reader opens the book to that page thereby serving as a means for conveying nonverbal communication within a verbal communication media. The identity of the reader (via the mirrored reflection of the reader&#39;s face) may be intended to coincide with the identity of a person to whom the book is dedicated. 
         [0006]    U.S. Pat. No. 1,804,487 (May 12, 1931, Yoshioka) discloses a mirror removably mounted on the inner surface of the cover of a book to serve as an agent through means of which one&#39;s personal appearance may be indicated. The mirror may be readily removed from place for the purposes of replacement or substitution.

       SUMMARY OF THE INVENTION 
       [0022]    The invention describes a portfolio, presentation folder, music folder or the like including one or more mirrors to permit the user to practice playing a musical instrument, singing or delivering other oral presentation while observing himself/herself in the mirror(s). The mirrored portfolio provides a folio with front and back covers attached together by a spine. One or more mirrors are positioned on the insides of the front or back covers in either a removably attached, hingedly attached or fixedly attached manner. In one embodiment, a primary mirror is attached to the inside of the back cover in a fixed position while a secondary mirror is positioned on the inside face of the front cover in hinged manner at its outer edge to permit it to swing outwardly from the folio to a desired angle. The folio may include one or more internal or external pockets for holding music, papers and the like. 
         [0023]    The present disclosure describes a notebook (which may be padded) having two mirrors (one or both may be hinged). The notebook is to be used as a practice tool for speakers, musicians, etc., and may be attached to a music stand or podium, and may include straps for securing it. 
         [0024]    The mirrored portfolio of the present invention includes a conveniently sized, portable mirror for use on any music stand or podium. In one embodiment, the invention is used as a practice tool for student and professional musicians. The invention may also be useful to public speakers as a practice tool. It is suitable for use at home, classroom settings, and discreet enough to be used during performance or live presentation if needed. The design is compact (fitting within a standard music folder, or presentation folio, etc.) and therefore is readily portable and stores easily. 
         [0025]    One embodiment of the present invention features a padded notebook. The notebook works as a frame for the mirror and carrying case when folded. In one embodiment, the notebook has the following dimensions when folded: Width 9.25 in.×Length 12.5 in.×Depth 0.75 in. The notebook may be outfitted with hook and loop fasteners, such as the Velcro brand on the outside of the notebook used to secure the two sides of the notebook together when used in a configuration requiring the front and back cover panels to be opened fully in a back to back manner. The notebook ideally employs a large flat mirror to service as the primary reflective surface. In the above-dimensioned notebook, ideal mirror dimensions are: Length 10 in.×Width 8 in. This large, flat mirror is attached to one of the inner covers of the notebook. A second, hinged mirror is the secondary reflective surface and provides an extended view as it may be opened into extended configurations. The mirror angle can be adjusted with the hinge and the mirror folds flat onto the inside cover for storage. One suitable set of dimensions for the secondary mirror is: Length 8 in.×Width 5 in. The hinged mirror is ideally attached to the inside of the other cover, about 0.5 in. from the edge of the notebook and is ideally centered along the length of notebook cover. A protective cloth cover is provided for the large mirror to help prevent scratching during storage. Buttons (or other fasteners) attached to notebook provide anchor for elastic security straps that can be used to keep the notebook in its closed position, or to assist in securing it into an open position on a music stand or podium. The elastic can be used to secure the mirrored notebook to the music stand to help prevent it from falling off during use. Also, the elastic may be used to keep the notebook closed during storage or travel. The elastic attached to the bottom right corner of the inside folder cover is approximately 17.25 in. The elastic attached to the inside at the center of right side of notebook is approximately 10.5 in. Other dimensions are possible. The notebook ideally contains a pocket on the side of the notebook used for storing sheet music or other papers. In use, the notebook can be turned upside down so that the flat mirror can be on the left and the hinged mirror on the right during use. Buttons or other attachment devices can be used to anchor the elastic closures (much like the button/elastic closures used on envelopes and folders. However, the elastic could be attached directly to the cover, e.g., by sewing thereby eliminating the need for buttons.

Also, embodiments of the present invention may also include one or more external pockets. 
         [0088]    In the embodiments depicted in  FIGS. 1A-1D  and  2 A, the front surface or face  20   a  of the first mirror  20  contains or otherwise projects a reflective mirror finish (of any variety known in the art) and the rear surface  20   b  of the first mirror  20  is mounted to the back cover inside face  14   a  using glue, adhesives, double sided adhesive tape, fasteners, hook and loop fasteners, clips, mirror clips, J-shaped mirror clips, picture frame turn buttons, magnetic mounts, hinges or the like. As such, the mirror  20  may be permanently affixed, movably affixed, or removably affixed to the back cover inside face  14   a . If the mirror  20  breaks, it can be replaced. The mirror  20  may be of any desired size and shape. In a preferred embodiment, the mirror  20  covers a substantial portion of the back cover inside face  14   a  such as illustrated in  FIG. 1A . In another embodiment, the mirror  20  covers all or substantially all of the back cover inside face  14   a . In one embodiment, the mirror  20  is mounted directly to the back cover inside face  14   a  such as illustrated in  FIG. 1B . In another embodiment, as illustrated in  FIG. 1C , the mirror  20  may also be mounted within a recessed area  14   h  of the back cover inside face  14   a  to permit the mirror  20  to be mounted flush with the back cover inside face  14   a , or countersunk into the recessed area  14   h . When the mirror  20  is mounted within the recessed area  14   h , this helps to further protect the mirror and its edges. 
         [0089]    Referring now to  FIGS. 3 ,  4 , and  5 A- 5 E, there are shown various representative arrangements illustrating how the first mirror  40 ,  50  or  60  may be hingably mounted to the back cover inside face  14   a.    
         [0090]    For example,  FIGS. 5A , and  5 C- 5 E show an embodiment wherein the first mirror  60  has a front surface  60   a , a rear surface  60   b , a top edge  60   c , a bottom edge  60   d  opposite the top edge  60   c , an inside edge  60   f  and an outside edge  60   e  opposite the inside edge. In this embodiment, the first mirror  60  inside edge  60   f  is hingably attached with a hinge device  62  to the back cover inside face  14   a  proximate the back cover inside edge  14   f  to permit the first mirror  60  to be rotated about its hinge  62  to a desired first mirror angle  6 . In one embodiment, the front surface  60   a  of the first mirror  60  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  60  is rotated about its hinge  62  to its right-most position. In another embodiment, the rear surface  60   b  of the first mirror  60  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  60  is rotated about its hinge  62  to its left-most position. In yet another embodiment, both the front surface  60   a  and rear surface  60   b  of the first mirror  60  contain or otherwise project a mirrored finish so that a mirrored finish will face the user when the first mirror  60  is rotated about its hinge  62  to either its leftmost or rightmost position. 
         [0091]    The first mirror  60  may be of any desired size and shape. In a preferred embodiment, the mirror  60  covers a substantial portion of the back cover inside face  14   a  such as illustrated in  FIGS. 5A and 5C . In another embodiment, the mirror  60  covers all or substantially all of the back cover inside face  14   a . In one embodiment, the hinge  62  for the mirror  60  is mounted directly to the back cover inside face  14   a  proximate to the back cover inside face  14   a  inside edge  14   f . In another embodiment, the hinge  62  for the mirror  60  is mounted directly to the back cover inside face  14   a  along the back cover inside face  14   a  inside edge  14   f  such as illustrated in  FIG. 1B . In another embodiment, the hinge  62  of the mirror  60  may be mounted to, or otherwise integrated into the spine or backbone  16  much like a leaf of the folio. In another embodiment, the mirror  60  may also be mounted within a recessed area  14   h  of the back cover inside face  14   a  to permit the mirror  60  to be mounted flush with the back cover inside face  14   a , or countersunk into the recessed area  14   h . When the mirror  60  is mounted within the recessed area  14   h , this helps to further protect the mirror and its edges. In one embodiment, the first mirror angle  6  ranges between about 0° and 180° when the hinge  62  is mounted proximate the rear cover inside edge  14   f . When the hinge  62  is mounted along the spine  16 , and where the spine angle  2  ranges between about 0° and about 360° then the first mirror angle  6  may also range between about 0° and about 360°. 
         [0092]    The first mirror may also be hingably connected to the folio in other configurations. For example, referring now to  FIG. 3  there is illustrated an embodiment wherein the first mirror  40  has a front surface  40   a , a rear surface  40   b , a top edge  40   c , a bottom edge  40   d  opposite the top edge  40   c , an inside edge  40   f  and an outside edge  40   e  opposite the inside edge. In this embodiment, the first mirror  40  inside edge  40   f  is hingably attached with a hinge device  42  to the back cover inside face  14   a  proximate the back cover outside edge  14   e  to permit the first mirror  40  to be rotated about its hinge  42  to a desired first mirror angle  6   a . In one embodiment, the front surface  40   a  of the first mirror  40  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  40  is rotated about its hinge  42  to a right-side (or open) position extending outward from the outer edge  14   e . In another embodiment, the rear surface  40   b  of the first mirror  40  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  60  is rotated about its hinge  42  to its left-most (closed) position. In yet another embodiment, both the front surface  40   a  and rear surface  40   b  of the first mirror  40  contain or otherwise project a mirrored finish so that a mirrored finish will face the user when the first mirror  40  is rotated about its hinge  42  to either its leftmost or rightmost position. 
         [0093]    The first mirror  40  may be of any desired size and shape. In a preferred embodiment, the mirror  40  covers a substantial portion of the back cover inside face  14   a  such as illustrated in  FIG. 3 . In another embodiment, the mirror  40  covers all or substantially all of the back cover inside face  14   a . In one embodiment, the hinge  42  for the mirror  40  is mounted directly to the back cover inside face  14   a  proximate to the back cover inside face  14   a  outside edge  14   e . In another embodiment, the hinge  42  for the mirror  40  is mounted directly to the back cover inside face  14   a  along the back cover inside face  14   a  outside edge  14   e . In another embodiment, the hinge  42  of the mirror  40  may be mounted to, or otherwise integrated into the rear cover outer edge  14   e . In another embodiment, the mirror  40  may also be mounted within a recessed area  14   h  of the back cover inside face  14   a  to permit the mirror  40  to be mounted flush with the back cover inside face  14   a , or countersunk into the recessed area  14   h . When the mirror  40  is mounted within the recessed area  14   h , this helps to further protect the mirror and its edges. In one embodiment, the first mirror angle  6   a  ranges between about 0° and 180° when the hinge  42  is mounted proximate the rear cover outside edge  14   e . When the hinge  42  is mounted along the outer edge  14   e  then the first mirror angle  6   a  may range between about 0° (where the mirror front surface  40   a  contacts the rear cover inside face  14   a ) and about 360° (where the mirror rear surface  40   b  contacts the rear cover outside face  14   b ). 
         [0094]    The first mirror may also be hingably connected to the folio in other configurations along either the top edge or bottom edge of the rear cover. For example, referring now to  FIG. 4  there is illustrated an embodiment wherein the first mirror  50  has a front surface  50   a , a rear surface  50   b , a top edge  50   c , a bottom edge  50   d  opposite the top edge  50   c , an inside edge  50   f  and an outside edge  50   e  opposite the inside edge. In this embodiment, the first mirror  50  top edge  50   c  is hingably attached with a hinge device  52  to the back cover inside face  14   a  proximate the back cover top edge  14   c  to permit the first mirror  50  to be rotated about its hinge  52  to a desired first mirror angle  6   b . In one embodiment, the front surface  50   a  of the first mirror  50  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  50  is in its closed position as shown in  FIG. 4 . In another embodiment, the rear surface  50   b  of the first mirror  50  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the right (first) mirror  50  is rotated upward about its hinge  52  to its up-most (open) position. In yet another embodiment, both the front surface  50   a  and rear surface  50   b  of the first mirror  50  contain or otherwise project a mirrored finish so that a mirrored finish will face the user when the first mirror  50  is rotated about its hinge  52  to either its closed or open positions. 
         [0095]    The first mirror  50  may be of any desired type, size and shape. In a preferred embodiment, the mirror  50  covers a substantial portion of the back cover inside face  14   a  such as illustrated in  FIG. 4 . In another embodiment, the mirror  50  covers all or substantially all of the back cover inside face  14   a . In one embodiment, the hinge  52  for the mirror  50  is mounted directly to the back cover inside face  14   a  proximate to the back cover inside face  14   a  top edge  14   c . In another embodiment, the hinge  52  for the mirror  50  is mounted directly to the back cover inside face  14   a  along the back cover inside face  14   a  top edge  14   c . In another embodiment, the hinge  52  of the mirror  50  may be mounted to, or otherwise integrated into the rear cover top edge  14   c . In another embodiment, the mirror  50  may also be mounted within a recessed area  14   h  (like shown in  FIG. 1C , for example) of the back cover inside face  14   a  to permit the mirror  50  to be mounted flush with the back cover inside face  14   a , or countersunk into the recessed area  14   h . When the mirror  50  is mounted within the recessed area  14   h , this helps to further protect the mirror and its edges. In one embodiment, the first mirror angle  6   b  ranges between about 0° and 180° when the hinge  52  is mounted proximate the rear cover top edge  14   c . When the hinge  52  is mounted along the top edge  14   c  then the first mirror angle  6   b  may range between about 0° (where the mirror rear surface  50   b  contacts the rear cover inside face  14   a ) and about 360° (where the mirror front surface  50   a  contacts the rear cover outside face  14   b ). 
         [0096]    Referring now to  FIGS. 1A ,  1 D,  2 A- 2 C,  3 ,  4  and  5 A, there is shown a representative arrangement illustrating how the second mirror  30  may be hingably mounted to the front cover inside face  12   a . For example, the second mirror  30  has a front surface  30   a , a rear surface  30   b , a top edge  30   c , a bottom edge  30   d  opposite the top edge  30   c , an inside edge  30   f  and an outside edge  30   e  opposite the inside edge. In this embodiment, the second mirror  30  inside edge  30   f  is hingably attached with a hinge device  32  to the front cover inside face  12   a  proximate the front cover outside edge  12   e  to permit the second mirror  30  to be rotated about its hinge  32  to a desired second mirror angle  7 . In one embodiment, the front surface  30   a  of the second mirror  30  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the left (second) mirror  30  is rotated about its hinge  32  to a left-side (or open) position extending outward from the outer edge  12   e . In another embodiment, the rear surface  30   b  of the second mirror  30  contains or otherwise projects a reflective mirror finish, i.e., the mirrored finish appears on the surface facing the user when the left (second) mirror  30  is rotated about its hinge  32  to its right-most (closed) position. In yet another embodiment, both the front surface  30   a  and rear surface  30   b  of the second mirror  30  contain or otherwise project a mirrored finish so that a mirrored finish will face the user when the second mirror  30  is rotated about its hinge  32  to either its leftmost or rightmost position. 
         [0097]    The mirror  30  may be of any desired type, size and shape. In a preferred embodiment, the mirror  30  covers approximately one-third to one-half of the front cover inside face  12   a  such as illustrated in  FIG. 1A . In another embodiment, the mirror  30  covers a substantial portion of the front cover inside face  14   a  such as illustrated in  FIG. 3 . In yet another embodiment, the left mirror  30  is smaller than the right mirror  20 . In another embodiment, the mirror  30  covers all or substantially all of the front cover inside face  12   a . In one embodiment, the hinge  32  for the second mirror  30  is mounted directly to the front cover inside face  12   a  proximate to the front cover inside face  12   a  outside edge  12   e . In another embodiment, the hinge  32  for the second mirror  30  is mounted directly to the front cover inside face  12   a  along the front cover inside face  12   a  outside edge  12   e . In another embodiment, the hinge  32  of the second mirror  30  may be mounted to, or otherwise integrated into the front cover outer edge  12   e . In another embodiment, the second mirror  30  may also be mounted within an optional recessed area  34  of the front cover inside face  12   a  to permit the second mirror  30  to be mounted flush with the front cover inside face  12   a , or countersunk into the recessed area  34 . The recessed area  34  has a bottom surface  34   a , a tabbed cut-out  34   b  for opening left side mirror, a top edge  34   c , a bottom edge  34   d , an outside edge  34   e  and an inside edge  34   f . When the second mirror  30  is mounted within the recessed area  34 , this helps to further protect the mirror and its edges. In one embodiment, the second mirror angle  7  ranges between about 0° and 180° when the hinge  32  is mounted proximate the front cover outside edge  12   e . When the hinge  32  is mounted along the outer edge  12   e  then the second mirror angle  7  may range between about 0° (where the mirror front surface  30   a  contacts the front cover inside face  12   a ) and about 360° (where the mirror rear surface  30   b  contacts the front cover outside face  12   b ). 
         [0098]    The mirrors used in the present invention are preferably constructed of a plastic material to minimize the potential for breakage or shattering, and to reduce the weight, but the mirror could be any suitable substrate capable of receiving a reflective coating. If a glass mirror is employed, it is preferred that it be a safety glass mirror having a special protective film on the back surface to prevent injuries in the event the mirror is broken. It is preferred that the mirrors used for the present invention be plane mirrors (those with flat reflective surfaces) so that they create virtual images of the same size as the original object. However, convex or concave mirrors could be used as may be desired. If desired, the one or more mirrors could be of a non-reversing mirror variety that provide a non-reversed image of its subject. The mirror(s) could be made from a plastic mirror sheet material, such as, e.g., mirrored acrylic, polystyrene, plexiglass, polycarbonate and the like such as those mirrored plastics offered by American Acrylics (www.americanacrylics.com), U.S. Plastics Corp. (www.usplastic.com) and Plaskolite, Inc. (Columbus, Ohio, www.plaskolite.com). For example, a ⅛-inch thick, or ¼-inch (or other thickness) acrylic or other plastic mirror could be cut to the desired size and shape for use in various embodiments disclosed herein of the first and second mirrors. Additionally, the plastic mirror could be double-sided (first surface/two-sided mirror) so that a mirrored/reflective surface is present on both sides of the mirror. Acrylic mirror sheets are the most popular lightweight and flexible mirror substrate available typically in the widest range of thicknesses. PETG mirror sheets are higher impact strength than acrylic and offers versatile fabrication properties with good impact strength, good design flexibility and speed of fabrication. PETG mirror is available in 0.030″-0.118″ in 48″×96″ sheets. The thinner PETG gauge sheet is ideal for the fabrication of children&#39;s toys, cosmetic uses and office supplies. Polycarbonate mirror sheets offer a very high impact strength. The optics of polycarbonate are comparable to acrylic, but its strength is 30 times stronger. 
         [0099]    Because acrylic has a relatively soft surface and is flexible, some imperfections or distortions may occur in a mirrored acrylic mirror. Visual distortion is a function of viewing distance and material thickness. As such, according to websites plaskolite.com and theplasticshop.co.uk, depending on the size of the mirror, when using a plastic mirror material, a thicker mirror is preferred to maintain better optical integrity by reducing the possibility that the mirror could bend and distort the image. Mirrored acrylic is a reflective film applied to a substrate. As such, when the substrate is affixed to another surface, both of the materials will in time conform to the underlying supporting surface irregularities, thus, when mounting the mirror on the cover of the folio, it is preferred that the mounting surface of the cover be a smooth, rigid, sturdy flat backing. When using screws or other mechanical attachment to attach the mirror to the folio, care should be used to evenly tighten down the mirror to minimize distortion. When using a plastic mirror, where the mirror will be adhesively attached to the folio cover, the adhesive selected should be one that does not attack the backing material of the mirror. One such suitable adhesive is a chemically-curing, solvent free sealant and adhesive combining the best qualities of silicone and polyurethane sealants, such as the “Mirror Mate” mirror adhesive product sold by www.theplasticshop.co.uk. The mirrors may also be obtained with an adhesive backing that transfers an adhesive on the sheet once its protective paper layer is pulled off. An adhesive backed mirror has advantages over adhesives that are applied by hand that can cause messy edges and non-uniform adhesive coverage. Other suitable adhesives and mirror attachment devices are known in the art. 
         [0100]    In another embodiment of the present invention, the mirrored folio further comprises a flexible protective material  22  for covering the first mirror, the flexible material having a topside outer surface  22   a , an underside surface  22   b , a top edge  22   c , a bottom edge  22   d , a right side edge  22   e  and a left side edge  22   f , the flexible material  22  being attached to the back cover inside face  14   a  to permit the protective material  22  to cover the mirror (e.g.,  20 ) (as shown in  FIG. 2A ) when the mirror is not in use and to be pulled back (as shown in  FIG. 1A ) to expose the mirror when the mirror is to be used, wherein the flexible protective material  22  may be selected from the group consisting of: synthetic cloth, natural cloth, flannel cloth, synthetic and natural cloth blends, soft suede-like material, plastic sheet material, rubber sheet material, and the like. The protective material may be mounted proximate the mirror in any number of ways, including, e.g., using adhesives, tape, sewing, and other fasteners, such as hook and loop fasteners. In the embodiment depicted in  FIGS. 1A and 2A , the protective cover  22  upper edge  22   c  is preferably mounted or attached proximate the mirror upper edge, e.g.,  20   c.    
         [0101]    The hinges  32 ,  42 ,  52  and  62  described herein used to secure one or more mirrors to the folio covers preferably are friction hinges to permit the mirrors  30 ,  40 ,  50  and  60  to be rotated about their hinge angles and to hold the mirrors in the desired position. The hinge(s) may be a single hinge (continuous hinge), preferably extending substantially the entire length of the mirror edge, or otherwise extending a sufficient distance along the edge of the mirror to support the mirror. The hinge may also comprise one hinge, or a plurality of spaced-apart hinges. Various hinges known in the art can be employed in the present invention, including those selected from the group consisting of: metal, plastic, rubber or cloth hinges, inset hinges, overlay hinges, variable overlay hinges, torsion hinges, concealed hinges, semi-concealed hinges, non-mortise hinges, Soss hinges, Sepa hinges, barrel hinges, knife hinges, pin hinges, clip top hinges, back-to-back wrap around hinges, continuous hinges, slotted piano hinges, wrap around slotted piano hinges, partial wrap hinges, inset hinges, fully concealed hinges, tray table hinges, pivot hinges, roto hinges, stop hinges, butt hinges, specialty hinges, double action hinges, pivot hinges, single pin hinges, stop hinges, staple hasp catch hinges, Blum brand hinges, slide rail hinges, fixed pin hinges, spring hinges, box hinges, flush hinges, mortise hinges, parliament hinges, fastener hinges, friction hinges, strap hinges, tee hinges, finial tipped hinges, ball tipped hinges, and other metal hinges offered by, e.g., Rockler Woodworking and Hardware (Medina, Minn., www.rockler.com); www.houseofantiquehardware.com; and www.hardwaresource.com; for example. Different metals may be employed as are known in the art, such as, for example, brass, aluminum and stainless steel. 
         [0102]    Additionally, plastic hinges, such as those made from flexible alloyed polymeric materials, modified polyolefin copolymers, or other plastics, acrylic, etc., may also be employed, such as, for example, the plastic pinless butt hinges and continuous hinges manufactured and sold by, e.g., C. E. Shepherd Company (Houston, Tex., www.ceshepherd.com). For example, these plastic hinges are advanced one-piece, molded, plastic, pinless hinges created for silent and maintenance-free service with never a need for lubrication. They will not fatigue or deteriorate even in wet or corrosive environments. Plastic hinges are available in continuous hinge style (similar to a piano hinge) or butt hinges in a range of standard sizes, and custom hinges can be molded to desired specifications. Other plastic hinges are available such as, for example, the acrylic hinges, piano hinges, polypropylene hinges, living hinges, and thermoplastic hinges (offset or flush) offered by U.S. Plastic Corp. (Lima, Ohio, www.usplastic.com) or the plastic hinges, piano hinges, butt hinges, and continuous hinges offered by Monroe Hinge &amp; Stamping Co. (Auburn Hills, Mich., www.monroeengineering.com). 
         [0103]    Also, cloth hinges could be used in the present invention to attach the mirrors to the folio. For example, glass cloth, fiberglass cloth, Kevlar brand cloth, or the cloth-bound hinges used on pressboard report covers, such as those made under the Universal brand, and other cloth hinge materials known in the art, including hinge tape materials, could be used. 
         [0104]    Rubber (or other similar materials) or rubber gasket glass hinges could also be employed in creating a hinge for attaching one edge of a mirror to the folio similar to the glass-to-wall rubber hinges offered by Custom Hardware Manufacturing, Inc. (CHMI)(Keokuk, Iowa, www.chmi.com, and described in U.S. Pat. No. 5,687,869, incorporated herein by reference). 
         [0105]    Additionally, other mechanisms for attaching the second mirror could be employed, including, a double retractable arm structure, a pivot arm structure, a telescoping structure and the like. 
         [0106]    The covers  12  and  14  may be constructed as with any folio, presentation folder, music folder, diary, day planner and the like, and can be made from any number of materials known and used in the art including, without limitation, plastics, nylon, vinyl, leather, rawhide, leatherette, faux leather, pressboard, synthetic materials, paper/cardboard, cloth and the like. Exemplary folders may include an internal structural layers such as a pressboard panels that are in-turn covered by an outside covering of choice, e.g., vinyl, leather, leatherette, etc. The PlanAhead brand of folios may be modified according to the teachings of the present invention to include the features described herein. The covers  12 ,  14  may employ brass reinforced corners (not shown). The size of the folio (outside dimensions) can vary according to the desired use. Also, Company Folders, Inc. (Keego Harbor, Mich., www.companyfolders.com) offers a wide variety of folders, binders, portfolios, presentation folders and the like that could be suitably outfitted with the mirrors according to the teachings herein to form a mirrored portfolio embodiments of the present invention. Additionally, Levenger Company (Delray Beach, Fla., www.levenger.com) carries a line of folios that could also be modified according to the teachings of the present disclosure to become mirrored portfolios of the present invention. 
         [0107]    The zippered style day planners described by White, U.S. Pat. No. 6,017,062 (which is incorporated herein by reference in its entirety for all purposes), and offered by The Mead Corporation, Dayton, Ohio, could also serve as an exemplary structure to modify according the present teachings to create a zippered, mirrored portfolio. In this case, where the planner is a ring binder style, the first mirror could be mounted on the inside back cover, or could be mounted on a page/leaf structure that could be hole-punched and inserted into the ring binder. Likewise, the second mirror could be hingably mounted on the inside front cover of the planner, or could be hingably mounted to a page/leaf that can be inserted into the ring binder. 
         [0108]    The mirrored portfolio or presentation folder/notebook may further comprise one or more closure devices or fasteners  4   a ,  4   b ,  4   c ,  8 , for securing the front cover to the back cover when the spine angle is either about 0° (where the front cover inside face faces the back cover inside face) and 360° (where the front cover outside face faces the back cover outside face), the closure devices being selected from the group consisting of hook and loop fasteners, clasp closures, snap closures, magnet closures, ties, ribbons, straps, elastic loops, elastic ties, buttons, zippers, belt with fastener, buckles, loop and belt strap enclosures, belt and buckle enclosures, belt and snap enclosures, and the like and other closure devices used on folios and notebooks as are known in the art (e.g., as shown in White, U.S. Pat. No. 6,017,062. The folio may also employ an external strap or handle  3  as may be desired. 
         [0109]    Also, the folio may also be equipped with one or more attachment devices (e.g.,  8 ) for securing the portfolio practice mirror to a stand, the one or more attachment devices being selected from the group consisting of ties, fasteners, hook and loop fasteners, straps, elastic loops, button fasteners, and clips. 
         [0110]    For example, music folders often are oversized (e.g., about 12 inches wide and 15 inches tall) compared with standard letter-size note folios. Exemplary custom leather music folders, such as the Pollock Leather Music Folder (www.stephen-pollock.com) could be outfitted with the mirrors according to the teachings herein to form a mirrored music folder embodiment of the present invention. 
         [0111]    Similarly, standard or padded music folders could also be modified according to the present teachings to create mirrored music folder embodiments of the present invention. For example, “The Black Folder” is a popular, lightweight, ergonomic choral music folder measuring 10¾ inches by 12½ inches, available from, e.g., The Music Mart, Inc. (Albuquerque, N. Mex., www.musicmart.com), and Small World Musicfolder.com Inc. (Vancouver, BC, www.musicfolder.com). This folder is a strong, heavy-duty construction with leatherette exterior (and interior pockets) for long durability. This folder employs a retainer strap on its interior bottom to prevent loose music from sliding out, and can also be used to holds the folder open. This folder also features a button on the folder to unsnap the bottom strap to open the folder wider. The folder also employs 10 elastic cords installed in an aluminum hinge to holds music in place for complete security. A separate ring binder, which can be threaded into the strings, can be added to the folder. The folder uses sewn edges (double-sewn on top and bottom), a heavy weight hand strap, and brass corners. This folder is also provided with two gusseted pockets with ½″ of expansion. Where the mirrored folio of the present invention is used by a person standing and holding the folder (e.g., a choral singer, a presenter, etc.) it is preferred that the mirrors be lightweight plastic material. Similar band and orchestra music folders are available and can be modified according to the present teachings herein to construct mirrored folio embodiments of the present invention from sources such as www.hickeys.com, www.protecmusic.com (padded music folders). 
         [0112]    In one embodiment (depicted generally in the cross-sectional views  FIGS. 1B ,  1 C,  2 B and  2 C), the back cover  14  and/or front cover  12  (not shown) may further comprise a layer of padding, e.g.,  14   g  (shown on back cover) and  12   g  (shown on the front cover). As such, as may be desired for aesthetics and/or to better protect the contents of the mirrored portfolio (including the mirror(s), a padded layer  12   g  may be employed between the front cover inside face  12   a  and the front cover outside face  12   b  and/or a padded layer  14   g  may be employed between the back cover inside face  14   a  and the back cover outside face  14   b . The padding material may be any suitable padding material, such as those padding materials used in existing padded folios, padded presentation folders, padded music folders, etc. and those selected from the group consisting of: foam, neoprene, quilt batting, felt, sueded polyethylene, polyester padding, air cell padding, and the like as are known in the art of folios. 
         [0113]    The spine or backbone  16  may be constructed in any number of ways, and have varying spine widths  16   a . For example, in one embodiment, the spine  16 , front cover  12  and back cover  14  may be formed from the same sheet of material. In another embodiment, the flexible spine or backbone  16  is simply formed by the joining together of front cover inside edge  12   f  to back cover inside edge  14   f . In one embodiment, the front cover  12  and back cover  14  are formed from a contiguous material, and the spine  16  is simply the vertical midpoint between the front cover outside edge  12   e  and the back cover outside edge  14   e . In yet another embodiment, the spine  16  is formed by creating a fold or crease at the juncture of the front cover inside edge  12   f  to the back cover inside edge  14   f . As will be understood, the width  16   a  of the spine  16  can be varied according to the desired volume of materials (sheet capacity) to be contained inside of the mirrored portfolio  10 . In another embodiment, the spine  16  is a substantially flat or partially curved, rigid surface having a left edge  16   b  that is attached (via flexible or hinged attachment) to the front cover inside edge  12   f  and a right edge  16   c  that is attached (via flexible or hinged attachment) to the back cover inside edge  14   f . In other embodiments, the spine  16  may be a hinge (as described herein or otherwise known in the art), a flexible material, a ring binder ringed notebook spine, a locking slant-D or round ring binder spine, a zippered binder spine, a presentation folder backbone, a folder single-score backbone, a folder double-score backbone, a folder triple-score backbone a velo-bound spine, a spiral bound spine, a twin loop wire binding, a comb binding, a ring binding, tape binding, saddle stitch binding, perfect binding, stapled binding, a music folder spine, a book bindery spine, and the like. 
         [0114]    The folio embodiments employing a hinged primary mirror may also be modified to create a storage area in the inside back cover  14   a  for storing papers, pencils, etc. The mirror would serve as a hinged covering for this storage area. 
         [0115]    In a preferred embodiment, the spine angle  2  is adjustable between about 0° (where the front cover inside face  12   a  faces, or touches, or is substantially parallel with the back cover inside face  14   a ) and about 360° (where the front cover outside face  12   b  faces, or touches or is substantially parallel with the back cover outside face  14   b ). The spine  16  can also be constructed as with the spines of typical folios, portfolios, padfolios, presentation folders, diaries, and the like. 
         [0116]    Referring now to  FIGS. 1D and 5E , there are disclosed examples of how two of the mirrored portfolio embodiments described herein might be used. In  FIG. 1D , the folio  10  can be placed on a stand (such as a music stand  70  having a base section  70   a , a vertical support section  72   b , and a horizontal ledge section  70   c  extending outward from the lower edge of the vertical support section  72 . In this embodiment, the folio  10  is opened much like a book, and is placed on the music stand  70  (or piano music ledge, speaker&#39;s podium, or is held by hand, etc.). The cover  22  is pulled back from the first (primary) mirror  20  to expose the reflective surface  20   a  so that the user may observe himself/herself while practicing or actually performing/presenting. As may be desired, the second (secondary) mirror  30  may be opened to a desired mirror angle  7  to provide an extended mirrored view. The folio may be equipped with straps, elastic or other attachment devices  8  to help secure the folio  10  to the stand  70   b . In  FIG. 5E  (and also referring to  FIGS. 5A-5D ), the folio  10   c  is displayed on a music stand  72  having a base,  72   a , a vertical support section  72   b  and a horizontal ledge section  72   c  extending outwardly from the vertical support section  72   b . The folio  10   c  is opened back on itself so that the outsides of covers  14  and  12  touch each other, and may be secured to each other via fasteners  4   a ,  4   b . The spine  16  of the folio  10   c  is placed on the music stand ledge  72   c  or other surface (e.g., podium, piano), and the primary mirror  60  (or  20  from  FIG. 1D ) faces the user. If the secondary mirror is hingedly attached to the folio  10   c , as in  FIG. 5E , the user may adjust the angle  6  of the primary mirror as may be desired. The angle adjustment can be useful particularly where the music stand (or podium or piano) is a fixed (non adjustable) angle. When finished, the user may store papers in the one or more pockets of the folio. The folio can then be closed, and if desired, fasteners may be used to keep the folio closed during storage or transport. The folio may have a carrying strap or handle  3  attached. The configuration shown in  FIG. 1D  is particularly advantageous for use with a musician using longer instruments, such as a violin or guitar. 
       Additional Embodiments 
       [0117]    In additional to the above, referring now to  FIGS. 7A ,  7 B,  9 A,  9 B,  9 C,  9 D,  9 E,  10 S,  10 B,  12 A,  12 B,  13 A,  13 B,  14 , and  15 , there is shown another mirrored practice portfolio  100 A employing removable insertable mirrored portfolio inserts. More particularly, the mirrored portfolio or folder (or presentation folder)  100 A of this embodiment comprises a front cover  120  having a front cover inside face  120   a , a front cover outside face  120   b , a front cover top edge  120   c , a front cover bottom edge  120   d  opposite the front cover top edge  120   c , a front cover outside edge  120   e , and a front cover inside edge  120   f  opposite the front cover outside edge  120   e . The mirrored portfolio or folder  100 A of this embodiment also comprises a back cover  140  having a back cover inside face  140   a , a back cover outside face  140   b , a back cover top edge  140   c , a back cover bottom edge  140   d  opposite the back cover top edge  140   c , a back cover outside edge  140   e , and a back cover inside edge  140   f  opposite the back cover outside edge  140   e . A flexible spine or backbone section  160  of width  160   a  hingedly connects or foldably joins the front cover inside edge  120   f  to the back cover inside edge  140   f  to permit the front cover  120  and back cover  140  to open and close about the hinged connection  160  along a desired spine angle  2  (such as shown in  FIG. 1A ). 
         [0118]    In this embodiment, the mirrored portfolio  100 A further comprises a first mirror  200  attached to the front cover inside face  120   a , the first mirror  200  having a front surface  200   a , a rear surface  200   b , a top edge  200   c , a bottom edge  200   d  opposite the top edge  200   c , an inside edge  200   f  and an outside edge  200   e  opposite the inside edge. The front surface or face  200   a  of the first mirror  200  contains or otherwise projects a reflective mirror finish (of any variety known in the art) and the rear surface  200   b  of the first mirror  200  is mounted to the front cover inside face  120   a  using glue, adhesives, double sided adhesive tape, fasteners, hook and loop fasteners, clips, mirror clips, J-shaped mirror clips, picture frame turn buttons, magnetic mounts, hinges or the like.

The mirror  200  may be of any desired size and shape. In a preferred embodiment, the mirror  200  covers a substantial portion of the front cover inside face  120   a  such as illustrated in  FIG. 7B . In another embodiment, the mirror  200  covers all or substantially all of the front cover inside face  120   a . In one embodiment, the mirror  200  is mounted directly to the front cover inside face  120   a  much like as illustrated in the embodiment of  FIG. 1B . In another embodiment, much like as illustrated in  FIG. 1C , the mirror  200  may also be mounted within a recessed area (not shown) of the front cover inside face  120   a  to permit the mirror  200  to be mounted flush with the front cover inside face  120   a , or countersunk into the recessed area. When the mirror  200  is mounted within the recessed area, this helps to further protect the mirror and its edges. 
         [0119]    In another embodiment of the present invention, the mirrored folio  110 A further comprises a flexible protective material  220  for covering the first mirror  200 , the flexible material having a an underside surface  220   a , topside outer surface  220   b , a top edge  220   c , a bottom edge  220   d , a right side (inside) edge  220   e  and a left side (outside) edge  220   f , the flexible material  220  being attached to the front cover inside face  120   a  to permit the protective material  220  to cover the mirror (e.g.,  200 ) (as shown in  FIG. 7A ) when the mirror is not in use and to be pulled back (as shown in, e.g.,  FIG. 7A ) to expose the mirror when the mirror is to be used, wherein the flexible protective material  220  may be selected from the group consisting of: synthetic cloth, natural cloth, flannel cloth, synthetic and natural cloth blends, soft suede-like material, plastic sheet material, rubber sheet material, and the like. The protective material  220  may be mounted proximate the mirror  200  in any number of ways, including, e.g., using adhesives, tape, sewing, and other fasteners, such as hook and loop fasteners. In the embodiment depicted in, e.g.,  FIGS. 7A and 7B , the protective cover  220  upper edge  220   c  is preferably mounted or attached proximate the mirror upper edge, e.g.,  200   c.    
         [0120]    The back cover inside face  140   a  further comprises one or more slits  300  having a slit width  300   a  for receiving a removable mirrored portfolio insert  230  into the space  140   g  behind the back cover inside face  140   a . In this embodiment, one slit may be horizontally disposed and located proximate and substantially parallel to the back cover top edge  140   c . One slit may be horizontally disposed and located proximate and substantially parallel to the back cover bottom edge  140   d . One slit may be vertically disposed and located proximate and substantially parallel to the back cover outside edge  140   e . In one embodiment, the back cover is outfitted with only one slit in a desired orientation. In another embodiment, the back cover is outfitted with two slits in desired orientations. In yet another embodiment, the back cover is outfitted with three slits as described above and as depicted in, e.g.,  FIG. 7A . The slits  300  provide an opening of length  300   a  into an interior space  140   g  existing or otherwise sandwiched between the back cover outer face  140   b  and the back cover inner face  140   a . As will be appreciated, other slit arrangements would be apparent to someone having the benefit of the present disclosure. For example, the back cover inside face  140   a  could employ a single diagonal slit (not shown) running from an area proximate the upper inside corner of the back cover inside face  140   a  downwardly and outwardly to an area proximate the lower outside corner of the back cover inside face  140   a.    
         [0121]    Referring now to  FIGS. 8A ,  8 B and  8 C there is depicted an exemplary removable mirrored portfolio insert  230  capable of being inserted into the slits  300  of the practice portfolio  100   a ,  100   b ,  100   c  and  100   d  described herein. More particularly, the removable mirrored portfolio insert  230  comprises an insert front cover  240  having an insert front cover inside face  240   a , an insert front cover outside face  240   b , an insert front cover top edge  240   c , an insert front cover bottom edge  240   d  opposite the insert front cover top edge  240   c , an insert front cover outside edge  240   e  of length  240   e - 1 , and an insert front cover inside edge  240   f  opposite the insert front cover outside edge  240   e . The removable mirrored portfolio insert  230  of this embodiment also comprises an insert back cover  250  having an insert back cover inside face  250   a , an insert back cover outside face  250   b , an insert back cover top edge  250   c , an insert back cover bottom edge  250   d  opposite the insert back cover top edge  250   c , an insert back cover outside edge  250   e , and an insert back cover inside edge  250   f  opposite the insert back cover outside edge  250   e . A flexible spine or backbone section  232  of width  232   a  hingedly connects or foldably joins the front cover inside edge  240   f  to the back cover inside edge  250   f  to permit the front cover  240  and back cover  250  to open and close about the hinged connection  232  along a desired spine angle (not shown). 
         [0122]    In this embodiment, the removable mirrored portfolio insert  230  further comprises a mirror or mirrored surface  260  attached to the back cover inside face  250   a , the mirror  260  having a front reflective surface  260   a , a rear surface  260   b , a top edge  260   c , a bottom edge  260   d  opposite the top edge  260   c , an inside edge  260   f  and an outside edge  260   e  opposite the inside edge. The front surface or face  260   a  of the mirror  260  contains or otherwise projects a reflective mirror finish (of any variety known in the art) and the rear surface  260   b  of the mirror  260  is mounted to the rear cover inside face  250   a  using glue, adhesives, double sided adhesive tape, fasteners, hook and loop fasteners, clips, mirror clips, J-shaped mirror clips, picture frame turn buttons, magnetic mounts, hinges or the like. As such, the mirror  260  may be permanently affixed, movably affixed, or removably affixed to the rear cover inside face  250   a . If the mirror  260  breaks, it can be replaced. The mirror  260  may be of any desired size and shape. In a preferred embodiment, the mirror  260  covers a substantial portion of the rear cover inside face  250   a  such as illustrated in  FIG. 8B . In another embodiment, the mirror  260  covers all or substantially all of the rear cover inside face  250   a . In one embodiment, the mirror  260  is mounted directly to the rear cover inside face  250   a  much like as illustrated in the embodiment of  FIG. 1B . In another embodiment, much like as illustrated in  FIG. 1C , the mirror  260  may also be mounted within a recessed area (not shown) of the rear cover inside face  250   a  to permit the mirror  200  to be mounted flush with the rear cover inside face  250   a , or countersunk into the recessed area. When the mirror  200  is mounted within the recessed area, this helps to further protect the mirror and its edges. 
         [0123]    As will be appreciated by one having the benefit of the present disclosure, the overall shape of the removable mirrored portfolio insert  230  is shown as a rectangular shape employing a rectangular-shaped mirror. The removable mirrored portfolio insert  230  could have any desired shape, including for example, square, oval or circular and the mirror could have any desired shape, including, for example, square, oval or circular. 
         [0124]    The one or more slits  300  of the practice portfolio  100   a ,  100   b ,  100   c  and  100   d  are designed to receive the removable mirrored portfolio insert front cover  240  in snug relationship in a space (not shown) between the portfolio back cover inside face  140   a  and back cover outside face  140   b . This is generally illustrated in  FIGS. 9A ,  9 B,  9 C,  9 D,  12 A,  12 B,  13 A,  13 B,  14 , and  20 . Where only one slot is present, a pocket can be designed and sized, with the slot as its opening, to receive the front cover  240 . Where multiple slits  300  are present, such as illustrated in, e.g.,  FIG. 7A , it will be appreciated that the back cover inside face  140   a  can be designed as an overlay sheet, with the desired slots cut into it, and then the overlay sheet is attached about its outer edges to the back cover  140  to create a space beneath inside face  140  to permit the front cover  240  to be inserted into the desired slit  300 . 
         [0125]    In another embodiment, the removable portfolio insert front cover  240  has one or more magnets  310   b  attached thereto or embedded therein. In this embodiment, the practice portfolios  100   a ,  100   b ,  100   c  and  100   d  are also outfitted with one or more magnets  310   a  inserted into or embedded within the back cover  140  oriented or positioned so that the polarity of magnet(s)  310   b  is attracted to the polarity of magnet(s)  310   a . The use of magnets can assist in holding the inserted front cover  240  in place, particularly when the mirrored section is opened for use, such as illustrated in  FIG. 9D . The magnets may be of any type, size and arrangement known in the art. In another embodiment, the magnets comprise a flexible magnetic sheet. The use of embedded magnets in the cover of the practice portfolio can also assist in securing the practice portfolio to a metal music stand or other metal surface. 
         [0126]    In another embodiment, such as shown in  FIGS. 7A ,  8 A,  8 B,  8 C,  9 A,  9 B,  9 C, and  9 D, the insertable portfolio  230  has a single magnet  310   b  centrally located within its front cover  240 , and the practice portfolios  100   a ,  100   b ,  100   c  and  100   d  have a corresponding single magnet  310   a  associated with each slit  300  located within the cover  140  to align with the magnet  310   b  when the removable portfolio  230  is inserted in the slit. In this orientation, the polarity of the magnets  310   a  and  310   b  are oriented so that the magnet  310   b  in the removable portfolio front cover  240  is magnetically attracted to the corresponding magnet  310   a  in the practice portfolio back cover  140 . 
         [0127]    Preferably, where multiple slits  300  are used, each slit has the same slit width  300   a . The slit width  300   a  should be at least the same length as the inside front cover edge height  240   e - 1 . In a preferred embodiment, the practice portfolios  100   a ,  100   b ,  100   c  and  100   d  contain three slits: one horizontal slit proximate the upper edge  140   c , one horizontal slit proximate the lower edge  140   d , and one vertical slit proximate the outer edge  140   e . The use of multiple slits provides the user with more potential mirror configurations. 
         [0128]    Referring again to  FIGS. 8A ,  9 B, and  8 C, in connection with  FIGS. 11 ,  12 A and  12 B, there is illustrated the use of an insertable clip or brace  350  that may be used, if desired, to assist in adjusting the degree to which the inserted portfolio  230  may be opened when in use. The clip  350  generally comprises a flat material, such as metal or plastic, of narrow width, and having opposed flat ends and a curved, central section forming a somewhat bow-like shape. As illustrated, the clip  350  comprises a first end  350   c , a second end  350   d , a top surface  350   a , bottom surface  350   b , and curved segments  350   e  and  350   f . When the inserted portfolio insert  230  is in use, the clip first end  350   c  is inserted into an opening  234  of width  234   a  located in the spine  232  (preferably at about the midpoint thereof) of the removable portfolio mirror insert  230  with the clip&#39;s bottom surface  350   b  facing outward as shown in  FIG. 12A . The insert  230  can then be opened (as illustrated in  FIG. 12B ) and the user can then adjust the depth that the clip  350  is inserted into the spine opening  234  to thereby adjust the angle to which the insert  230  is opened. 
         [0129]    Referring now to  FIGS. 10C ,  17 ,  18 ,  19  and  20  there is illustrated the use of an elastic strap or band  305  (having opposed ends  305   a ,  305   b ) that may be employed to maintain the practice portfolio  100 B closed when not in use (as shown in  FIG. 17 ), or as shown, to maintain the practice portfolio  100 B in a folded back position when desired. Preferably, the band  305  can be fixably attached to the portfolio  100 B. Additionally, referring also back to  FIGS. 1D and 5E , the elastic band can be employed to attach over a music stand to help secure the portfolio in place when in use with extended mirrors. 
         [0130]    Referring to  FIGS. 16 and 19 , there is illustrated the use of one or more loops  340  or other fasteners to, e.g., hold pencils  345 , pens (not shown) and the like. The loops may be made from any suitable material, including plastic, elastic, and the like. In one embodiment, each loop is a partial loop attached at opposed edges  340   a ,  340   b . The one or more pencil holder loops  340  are fastened to the practice portfolio  100 A,  100 B,  100 C,  100 D. In one embodiment, the one or more loops  340  are attached to the inside face  140   a  between the outer edge  140   e  and the slit  300 . In this embodiment, the user can also use one or more pencils or other objects in the loop(s)  340  to also serve as a stop for purposes of adjusting the angle of the opened portfolio insert  230  (e.g., as shown in  FIG. 20 ). 
         [0131]    Referring now to  FIGS. 17 and 18 , there is depicted a practice portfolio  100 C of the variety described herein equipped with external retractable handles  335  installed within the front and rear covers ( 120 ,  140 ) of the portfolio  100 C. In this embodiment, each handle comprises an upper horizontal member  335   a  (having upper edges  335   c ) located outside of the respective front or back cover  120   b ,  140   b , a lower horizontal member  335   d  located within a pocket (not shown) within the respective front or back cover  120   b ,  140   b , and two opposed vertical members  335   e ,  335   f  connecting the two horizontal members  335   a ,  335   d  and extending through cover slots  337 . The lower horizontal member  335   d  has an upper edge  335   g  that stops within the pocket against the slots  337  to prevent the handle from coming out of the cover when the handle is pulled outward in the direction of the arrow for use (as seen in  FIG. 18 ). When the handle is not in use, the handle top edges  335   c  are pushed downwardly to retract the handles into a retracted position shown in  FIG. 17 . The retractable handles depicted here are just exemplary. Other retractable handle designs will be apparent to those having the benefit of the present disclosure. 
         [0132]    Referring again to  FIGS. 19 and 20 , in another embodiment of the practice portfolio  100 D, snaps or magnetic snaps  320   a ,  320   b  may be attached in the inside corners of the portfolio  100 D to facilitate closure of the portfolio when not in use. For example, snaps  320   a  could be magnetic of one polarity, and the receiving snaps  320   b  could be magnetic of an opposite polarity. In another example, snaps  320   a  are standard snaps that are received into receiving snaps  320   b . In yet another embodiment, magnets could be embedded within the corners of the portfolio (generally in the location of  320   a ,  320   b ) to facilitate magnetically maintaining the portfolio in a closed position when desired (such as illustrated in  FIGS. 6 ,  17  and  18 ) and also in a reversed open position (as shown in  FIGS. 10B and 10C ). 
         [0133]    In view of the above disclosure, a versatile mirrored practice portfolio is disclosed. For example,  FIG. 9A  illustrates the use of a removable portfolio mirror insert  230  mounted in slit  300  located proximate the top edge  140   b  of the portfolio  100   a . This mirror insert  230  is shown in its closed position, but could be opened and used alone (as in  FIG. 9D ) or in conjunction with the mirror  200  on the opposite side of the portfolio (as in  FIG. 9E ). Likewise, the mirror  200  can be used while the mirror insert  230  is closed as depicted in  FIG. 13 . Similarly, as may be desired, the practice portfolio can be flipped over and used so that the mirror insert is on the left side and the mirror  200  is on the right side as illustrated in  FIG. 13 . A clip device  340  can also be employed to assist in adjusting the angle of opening of the mirror insert  230  as depicted in  FIGS. 11 ,  12 A and  12 B. 
         [0134]      FIG. 9B  illustrates the use of a removable portfolio mirror insert  230  mounted in slit  300  located proximate the outer edge  140   e  of the portfolio  100   a . This mirror insert  230  is shown in its closed position, but could be opened and used alone or in conjunction with the mirror  200  on the opposite side of the portfolio.  FIG. 9C  illustrates the use of a removable portfolio mirror insert  230  mounted in slit  300  located proximate the lower edge  140   d  of the portfolio  100   a . This mirror insert  230  is shown in its closed position, but could be opened and used alone or in conjunction with the mirror  200  on the opposite side of the portfolio. 
         [0135]      FIGS. 10A ,  10 B,  10 C illustrate how the practice portfolio  100   a ,  100   b ,  100   c ,  100   d  can be opened all the way so that the outer surfaces of the front and back covers are brought together. The user can the secure the practice portfolio into this folded back configuration using, e.g., the elastic band  305 . In its folded back position, the user can choose to use one side or the other as illustrated in  FIGS. 14 and 15 . 
         [0136]    Pencil holders and the like can be mounted in the practice portfolio as described above in connection with  FIGS. 16 and 19 . 
         [0137]    When the practice portfolio is not being used, it can be closed and secured by, e.g., elastic band, snaps, or other closure devices, and can then be carried in hand or in a backpack like a portfolio, or handles can be employed ( FIGS. 6 ,  18 ) to carry it like a briefcase. 
         [0138]    As will be understood by those having the benefit of the present disclosure, the present practice portfolio can also be used in conjunction with sheet music or other written materials, such as a book, that can be clipped to the notebook. Similarly, electronic devices, such as, an iPhone® smart phone or other like device or an iPad® tablet, or the like, can also be suitably attached to the practice notebook, e.g., via one of the slits, while still permitting use of the one or more slits to receive a mirrored portfolio insert. In one such embodiment, the practice portfolio can also serve as a carrying case for such electronic smartphone or electronic tablet device.
