CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application claims the benefit of U.S. Provisional Patent Applications No. 60/554,000 filed Mar. 16, 2004 and 60/558,442 filed Mar. 31, 2004. 
    
    
     TECHNICAL FIELD 
     This invention concerns albums for photographs and similar collectable items. 
     BACKGROUND 
     One type of high-quality loose-leaf album comprises a pair of covers enfolding a plurality of replaceable leaves for photographs or similar memorabilia, the covers and leaves being laced together by straps which lace through hinge elements projecting from the leaves, and also through slots in holders attached to the inside of the covers. The cover holders frictionally hold the ends of the straps. See, for example, U.S. Pat. No. 5,848,851 (Gunasekera). 
     SUMMARY OF THE INVENTION 
     The invention is an album for photographs and similar collectable items, having a cover in which at least one window is formed for the display of a photograph or other flat object. The displayed object is held in a pocket, which is formed from an upper transparent polymeric material that has been adhered or otherwise attached around three sides of its perimeter to a lower material (preferably paper), which in turn is completely affixed to the inner base card layer of the cover. A framed cutout in the cover displays the object, recessed within the cover due to the depth of the material forming the cover. 
     In particular, the invention is an album for photographs, having at least one cover in which at least one window opening is formed, in which the window is formed by a window frame mounting base having a L-shaped cross-sectional profile and inserted into the window opening from an inside of the cover. The album further comprises a window frame cover having a L-shaped cross-sectional profile that is inverted with respect to the profile of the window frame mounting base. The window fram cover is inserted into the window opening from an outside of the cover, and mates with the window frame mounting base such that outer-facing portions of the window frame cover exposed edges of the window frame mounting base. Thus, no seams are visible in normal use, as viewed from the outside of the cover, even when the album is viewed from an angle.

     DETAILED DESCRIPTION 
     In general terms, the invention is an improved version of the photograph album disclosed and claimed in U.S. Pat. No. 5,848,851 (Gunasekera), the entire contents of which are incorporated by reference. Unless specified otherwise below, the construction of the invention is as described in the Gunasekera patent. 
     The invention further includes a window formed in the material of one or both of the front and back covers of the album, preferably the front cover. The location of the window is not critical to the scope of the invention, but it is preferred for aesthetic reasons to place the window generally centered both horizontally and vertically in the front cover. The shape of the window is not critical to the scope of the invention but it is preferred that it be rectangular. The orientation of the window is not critical to the scope of the invention but it is preferred that it be portrait, as opposed to landscape. The size of the window is not critical to the scope of the invention, but for an especially preferred rectangular and portrait window centered on the front of a cover measuring approximately twelve inches in width (not including the spine of the album) and approximately twelve and one-half inches in height, a window having inside dimensions of five and one-half inches in height and three and one-half inches in width is preferred. 
     The size of the window frame is not critical to the scope of the invention, but for the especially preferred rectangular and portrait window just described, a window frame width of approximately seven-sixteenths inch on all visible exterior sides is preferred. The depth of the window frame is not critical to the scope of the invention, and will be dictated by the available thickness of the cover itself, but for the especially preferred rectangular and portrait window just described, a window thickness of approximately one quarter inch is preferred; the thickness of the window preferably is created by one leg of an L-shaped frame, as described farther below, and thus is a unitary piece constructed of the same material so that there are no seams or joints visible from the exterior of the album. The finish of the window frame is not critical to the scope of the invention, but for a dark colored album cover, a glossy silver finish is preferred. 
       FIG. 1  is a front view of album cover  10 , which has been opened up and laid flat to show in this single view the exterior of each of front cover  1 , window frame  2  located in front cover  1 , back cover  3 , and flexible backbone  4 . Front cover  1 , back cover  3 , and flexible backbone  4  are separate pieces which are assembled into an album by inserting opposite ends of flexible backbone  4  into the respective interiors of front cover  1  and back cover  3 . 
       FIG. 2  is a front view of a portion of front cover  1 , specifically the inner base card  5  that lies within front cover  1 . (Another inner base card  5  lies within back cover  3 .) As can be seen in the detail portion of the figure denoted A, this piece is slotted so that the strap that will hold the removable leaves within completed album  10  will also pass through the slots in the covers, as is known from the Gunasekera patent noted above. 
       FIG. 3  is a detailed dimensioned view of inner base card  5  (without slots as just described). Pocket  6  is formed from a lower layer  7  formed from a photo-safe material (e.g., paper), while upper layer  8  is typically transparent (it could be merely translucent) but otherwise is also a photo-safe material such as polypropylene or polyester. Because upper layer  8  will be ultimately exposed to the outside of the album, it should be a material that can withstand conditions such as exposure to sunlight (in terms of fading, yellowing, wrinkling, other disadvantages caused by light exposure and/or elevated temperatures, etc.) without losing its ability to both display and protect the underlying photograph or other object in pocket  6 . The two layers  7 ,  8  are fused or otherwise adhered together on three sides in adhesive region  9 , such as by thermal lamination or by use of a separate adhesive material, including UV-curable adhesives (although other types of adhesives may be employed). The fourth side is open so that the photograph or other displayed object may be inserted and removed. Pocket  6  is adhered or otherwise permanently attached to inner base card  5 , preferably by applying an adhesive with a removable liner to the back side of the photo pocket  6 . The liner is removed, and the photo pocket is applied to the base card. Regardless of how it is attached, it must be aligned with the window so that, once the entire album front cover is assembled, the contents of pocket  6  may be viewed through the window  2  of the front cover  1 . This step may be incorporated into the process of assembling the remainder of the album, or it may be done separately so that an inventory of pre-assembled units is provided. 
       FIG. 8  illustrates the assembled front cover, including dimensions for the preferred embodiment, although the scope of the invention is not limited to these dimensions. The back cover is the same as the front cover, but without the window, and thus is not shown but should be understood as part of an assembled album. The preferred components and construction of the front cover are illustrated in detail A of  FIG. 8 : window frame  101 , preferably but not necessarily manufactured of zinc alloy; window frame mounting base  102 , preferably but not necessarily manufactured of stainless steel, and to which window frame  101  attaches to form window  2  of  FIG. 1 ; inner base card  5 ; pocket  6 ; lower cardboard  106 ; sponge or foam board  107 ; upper cardboard  108  (which may or may not be necessary depending on the application), and exterior cover material  109 . The composition of these materials is not critical to the scope of the invention, and also would be understood by those skilled in the art of manufacturing album covers of this type. 
       FIG. 4  is a detailed view of components such as sponge or foam board  107 , upper cardboard  108 , and the like, illustrating that each has a hole, punched or cut in a conventional manner, and having the required size and location to accommodate window  2  and its other components. An appropriate set of one or more cuts or cutouts is made in exterior cover material  109  to be compatible with the holes formed in the other components of the cover. Exterior cover material  109  may be laminated or adhered to foam board  107 , upper cardboard  108  (if used), and the like along the perimeter of window  2  using conventional techniques. 
     Referring back to  FIG. 8 , the window frame  2  is assembled from the window frame  101  and window frame mounting base  102 , which are shown in more detail in  FIGS. 9 and 10 , respectively. In cross section, each piece is L-shaped, such that the window frame mounting base  102  is inserted into the window opening from below, and the window frame  101 , its L-shaped profile inverted with respect to the profile of the lower piece, is then inserted into the window opening from above, and the two pieces connect together. This enables the portions of the outer-facing window frame  101  to cover the exposed edges of the window frame mounting base  102 , thereby revealing no seams in normal use as viewed from the exterior front of the album, even when the album is viewed from an angle. 
     The window frame  101  and window frame mounting base  102  connect together in any convenient manner that does not expose seams or other construction features, as described above. The preferred technique for connecting the two pieces together uses one or more teeth  110  formed in any or all of the downwardly directed legs  111  of window frame  101 . In the preferred embodiment, there are two teeth  110  formed in each of the four downwardly directed legs  111 , but the number of teeth per leg and the number of legs having such teeth are each matters of preference and not limitations of the scope of the invention. Also, the preferred teeth are separate from each other and located generally toward the corners of the window frame  101  (i.e., near where adjacent downwardly directed legs  111  meet), but these are also preferences and not requirements of the invention. For example, an elongated ridge that extends over much or all of the extent of a downwardly directed leg  111  is within the scope of the invention. Similarly, a pair of teeth, matched in size and shape or not matched if so desired, could be provided adjacent each corner. 
     Mating features  120  are provided in upwardly directed legs  121  of the window frame mounting base  102 . The features are sized and located to provide a snap fit with the teeth  110  of window frame  101 . In the preferred embodiment, there are two openings  120  formed in each of the four upwardly directed legs  121 , but the number of openings or other snap features (such as a ridge or groove) per leg and the number of legs having such features are determined by the need for the two frame pieces  101  and  102  to be compatible with each other. Also, the preferred openings are discrete and separate from each other, again located generally toward the corners of the window frame mounting base  102 , but as before these are also preferences and not requirements of the invention. For example, an extended slot or ridge that extends over much or all of the extent of the upwardly directed leg  121  is within the scope of the invention. The size, number, configuration and the like of teeth  110  and openings  120  may be selected to balance ease of construction, the integrity of the finished product, and similar product design considerations, all while remaining within the scope of the invention. 
       FIGS. 11-13  are similar to  FIGS. 8-10 , respectively, with like numbered components corresponding to each other and illustrating an alternative embodiment in which the shape of a window is a heart instead of a rectangle. This embodiment also features discrete tabs, as opposed to a feature that runs the entire length of a side of component of the frame, house teeth  110  and mating features  120 . The use of discrete tabs is not limited to the heart shaped embodiment, and therefore could be employed in the rectangular shaped embodiment of  FIGS. 8-10  or in any other embodiment of the invention having a differently shaped frame. This set of figures also illustrates that the window frame may, in general, be curved as opposed to rectilinear. Thus, ovals, circles, squares, triangles, flower shapes, and other figures are within the scope of the invention even though they are not specifically illustrated. 
     The exterior cover material  109  may be gathered around the four exterior sides of the front cover and adhered underneath the visible exterior of the front cover using conventional techniques, such as pulling it taught and adhering it in place. On the side from which the base card  5  extends, the cover material  109  is adhered to the bottom side of lower cardboard  106  so that the slotted portion of base card  5  may extend outward from the front cover; access to the insert or remove the photograph is available on the other (upper) face of base card  5  but below the exterior cover material  109  and the bottom side of lower cardboard  106 . (This is also the location into which the backbone  4  is inserted, as described elsewhere, and thus backbone  4  lies atop the entrance to pocket  6 .) On the other three sides, the exterior cover material  109  may be adhered to the bottom side of lower cardboard  106 , and optionally (but preferably) the edges of exterior cover material  109  are covered by a suitable back piece (not shown) that also serves as the visible interior of the entire front cover. The back piece is adhered around as least its perimeter to the exterior cover material and/or the bottom face of lower cardboard  106 . 
       FIGS. 5-7  are views of the components of the backbone.  FIG. 5  shows front and back views of the backbone, which comprises a base backbone material  50  (such as a flexible card stock) to which has been adhered, using any convenient method, and a backbone bookcloth  51  (which typically is the same material as the exterior cover material  109  used on the front and back covers).  FIGS. 6 and 7  show dimensions for these materials in the preferred embodiment, but backbones having other configurations and dimensions are possible in other embodiments of the invention.
