     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to FIGS. 1 through 6, there is illustrated a display device which includes a back panel 12 and a front frame 14. The front frame 14 defines a display area of an enclosed article, which is typically a picture or document, and may have a wood grain or other decorative effect applied to its outwardly face. The height and width of the front frame 14 may vary with the size and shape of the article to be displayed, but generally the major axes of the display device will be orthogonal to one another. 
     It will be noted that the outer peripheral edges of the back panel 12 and the front frame 14 are substantially coextensive. The back panel 12 is provided with a plurality of raised ribs 16 extending along three of its marginal edges such that when the front frame 14 is placed over the back panel 12 in a manner causing the respective marginal edges to coincide, the plurality of ribs 16 contact only the inner surface of the front frame 14 in FIG. 2. In the centers of two adjacent edges of the inner surface 18 of the back panel 12 are formed tab receiving chambers 20a and 20b to be used when the display device is in the free standing mode described below. 
     The front frame 14 and the back panel 12 are typically secured together with a suitable adhesive. The plurality of ribs 16 act as spacers between the front frame 14 and the back panel 12. The thickness of the plurality of ribs 16 should be such that the pocket formed by the front frame 14, the back panel 12, and the plurality of ribs 16 is sufficiently wide to receive the articles or document to be displayed, but not so excessively great as to allow the article to wrinkle or curl within. 
     The rear surface of the back panel 12 is provided with an adapter element 22. The adapter element 22, clearly illustrated in FIGS. 1 and 4, is typically secured to the back panel 12 with a suitable adhesive. The adapter element 22 includes a pair of V-shaped apertures 24 and 26 and a pair of slots 28 and 30 formed in the material. The adapter element 22 should be oriented such that each of the slots 28 and 30 opens towards and is axially aligned with a respective tab receiving chamber 20a or 20b in the back panel 12, as illustrated in FIG. 2. The aperture 24 may be used to hang the display device so that one of its major axes will be in a generally horizontal position. The aperture 26 may be used to hang the display device so that the other of its major axes will be in a generally horizontal position. Any suitable means for hanging the display device, such as a nail or hook, may be used for support so that the selected aperture 24 or 26 receives the nail or hook and engages it securely in the apex of the V-shaped section to properly orient the device. Thus, the display device may be securely supported in either of the above hanging modes. 
     The display device may also be employed as a free standing element, such as commonly found on a table or desk top. For this mode, a support member 32 is utilized. The support member 32 consists of an upper tab 34, a strut 36, a foot 38, and a lower tab 40, each section being connected to the adjacent section by a webbed hinge clearly illustrated in FIGS. 5 and 6 and well known to those skilled in the art. The display device may be arranged for the free standing mode by inserting the upper tab 34 of the support member 32 into the desired slot of the adapter element 22 for example, slot 28. The lower tab 40 of the support member 32 is inserted into the corresponding and axially aligned tab receiving chamber 20b in the back panel 12. Likewise, if the other axis is desired to be placed in the horizontal position, the upper tab 34 is inserted into slot 30 of the adapter element 22, and the corresponding tab receiving chamber 20a receives the lower tab 40. Thus, the display device may be hung or stood upon either of its major axes. 
     The front frame 14, the back panel 12, and the adapter element 22 may be preferably fabricated from inexpensive thermoplastic materials, such as polystyrene, while the support member 32, because of the nature of its intended function, is typically fabricated from a fatigue resistant material, such as polypropylene or high density polyethylene. Conventional adhesives or thermal autogenous bonding methods may be used to attach the front frame 14 and the adapter element 22 to the back panel 12. The support member 32 is removably secured to the display device, thus eliminating the problems attendant with the use of adhesives or other bonding methods on non-similar materials. 
     Referring to FIGS. 7 through 9, there is illustrated a display device which includes an alternate embodiment of an adapter element 42. The adapter element 42 is typically secured to the rear surface of a panel 44. The panel 44 may typically be a plaque having indicia on the front surface which is to be displayed. As will be discussed, the adapter element 42 permits the panel 44 to be displayed in either the hanging mode or in the free standing mode. 
     The adapter element 42, clearly illustrated in FIGS. 8 and 9, includes a V-shaped aperture 46 and a slot 48 formed in the main body portion thereof, and a tab receiving chamber 50 formed in the peripheral edge portion thereof. 
     The adapter element 42 also includes a plurality of spaced apart parallel ribbed elements 52 formed on the one surface of the adapter element 42 which is to be secured to the rear surface of the panel 44. The ribbed elements 52 function to space the adapter element 42 away from the panel 44 such that the rear surface of the panel 44 cooperates with the adapter element 42 to provide the slot 48 and the chamber 50 with dimensions suitable for receiving the respective tabs of the support member 32. The ribbed elements 52 also provide clearly defined surface areas to which a suitable adhesive can be applied for securing the adapter element 42 to the rear surface of the panel 44. 
     The adapter element 42 is typically positioned on the rear surface of the panel such that the tab receiving chamber 50 is located along the lower marginal edge of the panel 44. Thus, if the panel 44 is to be displayed in the hanging mode, a suitable hook means may be used to engage the apex of the V-shaped section of the aperture 46 such that the front surface of the panel 44 is properly oriented. 
     If the panel 44 is to be displayed in the free standing mode, the support member 32 illustrated in FIGS. 5 and 6 is utilized. The upper tab 34 of the support member 32 is inserted into the slot 48 while the lower tab 40 is inserted into the tab receiving chamber 50. Thus, the display device may be employed as a free standing element on a desk or table top, for example. 
     One of the inherent advantages of the adapter element 42 is that the tab receiving chamber 50 for receiving the lower tab of the support member 32 is an integral portion thereof. This structure thus eliminates the need for forming a tab receiving chamber in the marginal edge of the attendant panel. Thus, the adapter element 42 can easily be utilized for displaying a single panel article such as a plaque. 
     The adapter element 42 and the panel 44 may be preferably fabricated from relatively inexpensive thermoplastic materials, such as polystyrene. Conventional adhesives or thermal autogenous bonding methods may be utilized to attach the adapter element 42 to the panel 44. 
     It will be seen from the above detailed description of the preferred embodiment that the present invention provides an inexpensive photo mount or other document holder with a unique hanging and support means which eliminates many disadvantages of the prior art described above. It will also be seen that the advantages of the present invention may be used with frame shapes other than rectangular, such as oval or round shapes or other desired geometries. Various other advantages of the present invention will be apparent to those skilled in the art and various modifications may be made without departing from the scope and spirit of the attached claims.
