     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0011]    For the purposes of promoting an understanding of the principles of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the disclosure is thereby intended, such alterations and further modifications in the illustrated device, and such further applications of the principles of the disclosure as illustrated therein being contemplated as would normally occur to one skilled in the art to which the disclosure relates. 
         [0012]    The present disclosure is directed to articles providing non-magnetic, releaseable adherence to surfaces to allow for the display of such articles. In certain embodiments, the articles can include a backing composed of polyvinyl chloride material to provide frictional or “tacky” adherence to certain surfaces. The polyvinyl chloride material backing may be useful for adherence to glass, mirrors, stainless steel, and other substantially non-ferromagnetic surfaces. Additionally, the polyvinyl chloride material backing can include an adhesive layer or coating on one side to provide for substantially permanent adhesion to the item to be displayed. 
         [0013]    Referring to  FIG. 1 , there is shown a side view of an article  10  according to one embodiment of the present invention. Article  10  non-magnetically and releasably adheres to surface  12 . Article  10  includes a display item  14  having a backing layer  16  composed of polyvinyl chloride material. In the illustrated embodiment, item  14  is substantially permanently attached to backing layer  16  via an adhesion coating or layer  18 . Accordingly, the entire article  10 , including item  14  attached to backing layer  16  via adhesion layer  18 , may be selectively removed from and placed on surface  12 , as often as desired by a user, for the life of the polyvinyl chloride material. 
         [0014]    As illustrated, item  14  includes a front surface  14   a  and a back surface  14   b,  backing layer  16  includes a front surface  16   a  and a back surface  16   b,  and adhesive layer  18  includes a front surface  18   a  and a back surface  18   b.  In preferred embodiments, back surface  16   b  of backing layer  16  selectively and releasably adheres to surface  12 . Additionally, front surface  18   a  of adhesive layer  18  permanently adheres to back surface  14   b  of item  14 , and back surface  18   b  of adhesive layer  18  permanently adheres to front surface  16   a  of backing layer  16 . Accordingly, front surface  14   a  of item  14  may be visible and on display. 
         [0015]    In certain embodiments, back surface  14   b  or display item  14  is a substantially rigid backing or support piece, such as a cardboard material as an example. In such cases, the adhesive material comprising adhesive layer  18  is applied to the cardboard backing or support piece of item  14 . In certain embodiments, the adhesive material may be a type of glue. 
         [0016]    Polyvinyl chloride material, used as backing layer  16 , is advantageous in its ability to releasably adhere to certain substantially non-ferromagnetic surfaces, such stainless steel, glass and mirrors, as examples. In the present disclosure, “non-ferromagnetic” refers to surfaces that are not attracted by a magnet. Polyvinyl chloride material adheres to many surfaces, yet leaves no adhesive residue on the surface upon removal of the item. Additionally, polyvinyl chloride material may be wiped down, dried and reused without affect to its adherence ability, and resists loss of adhesion due to moisture such as rain, sweat and condensation, as examples. Moreover, polyvinyl chloride material provides for sufficient adherence to certain surfaces, such that the items may remain on display for extended periods of item, while also allowing for easy removal and re-adherence of the items as desired. To that end, the polyvinyl chloride material allows for the items to be repeatedly adhered to and removed from the non-ferromagnetic without substantial loss to its adherence ability. In the present disclosure, the polyvinyl chloride material used as backing layer  16  is a sufficiently flexible piece of polyvinyl chloride foam or sponge material. 
         [0017]    Polyvinyl chloride material is substantially resistant to ultraviolet rays, most solvents and chemicals, fungi, oxidation and weathering. Additionally, polyvinyl chloride material is a long-life material which retains the ability to adhere to certain surfaces for an extended period of time. Polyvinyl chloride material is advantageous as a backing layer due to its numerous beneficial properties, including its adherence ability, stiffness, strength and weight, as examples. In certain embodiments, the polyvinyl chloride material used as backing layer  16  may include a quantity of plasticizing agent incorporated therein to soften the material and increase its adherence capabilities. 
         [0018]    It is contemplated that the amount of backing layer  16  that is substantially permanently adhered to item  14  may vary. As illustrated in  FIG. 2A , backing layer  16  may substantially cover back surface  14   b  of item  14 . In certain other embodiments, as illustrated in  FIG. 2B , backing layer  16  may include relatively thin strips of polyvinyl chloride material positioned adjacent the perimeter of item  14  on back surface  14   b.  To that end, it should be appreciated that backing layer  16  may be positioned on back surface  14   b  of item  14  in various other manners and configurations. In certain embodiments, it may be desirable to provide an increased surface area of backing layer  16  to increase the strength and integrity of the adherence of item  14  to the particular surface. Additionally, it is contemplated that adhesion layer  18  may be composed of various substantially permanent adhesion compositions and/or materials as would generally occur to one skilled in the art, to provide for the substantially permanent adhesion of backing layer  16  to item  14 . 
         [0019]      FIG. 3  illustrates only a few examples of the numerous items that may be displayed on a surface, including various substantially non-ferromagnetic surfaces, via a backing layer formed of polyvinyl chloride material. In the illustrated embodiment, photo frame  32 , medicine pill box  34 , alphabet letters  36 , notepad  38  and dry erase board  40  are adhered to stainless steel refrigerator surface  30  via backing layers of polyvinyl chloride material. The photo frame may include a substantially rigid cardboard support backing, with a material overlay piece attached to the cardboard support backing. In certain embodiments, the material overlay piece can be imprinted with a desired design using a silk screening process. Additionally, in certain embodiments the dry erase board includes a pen  42  and an erase  44  magnetically adhered to the board. 
         [0020]    In preferred embodiments, the displayed items are substantially planar such that they are configured to lay substantially flat against the non-ferromagnetic surface. The substantially planar configuration of the displayed items assists in preventing the items from being accidentally knocked off the non-ferromagnetic surface, as items which stick farther out from the surface having an increased chance of being accidentally knocked off. Additionally, the substantially planar configuration provides for increased surface area contact of the polyvinyl chloride foam backing layer on the item with the non-ferromagnetic surface to provide increased adherence of the display item to the surface. 
         [0021]    In certain embodiments, various articles having regular geometric shapes may be adhered to certain surfaces via polyvinyl chloride material backing layers. Examples of such articles include, but are clearly not limited to, framed articles, picture frames, bulletin boards, dry erase boards, chalk boards, paper note pads and children&#39;s reward charts. Additionally, in certain embodiments, container articles may be adhered to certain surfaces via polyvinyl chloride material backing layers. The container articles may include, as examples only, spice jars, medicine pill boxes, vitamin jars, salt and pepper containers, facial tissue boxes, writing instrument holders, and open containers for holding letters and other mail. In some embodiments, irregularly shaped articles may be adhered to certain surfaces via polyvinyl chloride material backing layers. Such articles might include alphanumeric character sets, decorative items, holiday decorations, children&#39;s characters, irregularly shaped note pads, thermometers, and other such irregularly shaped articles which lend themselves to surface adherence via polyvinyl chloride material backing layers. 
         [0022]    In alternative embodiments, backing layer  16  may be composed of a type of silicone tape material to provide the frictional or “tacky” adherence to non-ferromagnetic surfaces. In addition to the polyvinyl chloride foam material, the silicone tape backing may be useful for adherence to glass, mirrors, stainless steel, and other substantially non-ferromagnetic surfaces. Similar to the embodiment described above, the silicone tape backing can include an adhesive coating or layer  18  on one side to provide for substantially permanent adhesion to the item  14  to be displayed. 
         [0023]    Silicone tape material is also advantageous in its ability to releasably adhere to certain substantially non-ferromagnetic surfaces, such stainless steel, glass and mirrors, as examples. Silicone tape material adheres to many surfaces, yet leaves no adhesive residue on the surface upon removal of the item. Additionally, silicone tape material may be wiped down, dried and reused without affect to its adherence ability, and resists loss of adhesion due to moisture such as rain, sweat and condensation, as examples. Moreover, silicone tape material provides for sufficient adherence to certain surfaces, such that the items may remain on display for extended periods of item, while also allowing for easy removal and re-adherence of the items as desired. 
         [0024]    In certain embodiments, a type of silicone tape material which may be used is a white silicone rubber-coated glass fabric with a high temperature silicone adhesive. In such embodiments, the silicone tape material may include an inner layer of tightly woven fiberglass which is impregnated with silicone rubber. Additionally, a silicone adhesive may be coated onto one side of the inner layer. In certain embodiments, the silicone tape material may further include one or more layers of silicone rubber on opposite sides of the inner impregnated layer. The silicone adhesive provides excellent adhesion at varying temperatures, yet removes from surfaces cleanly. Silicone tape material is advantageous as a backing layer due to its numerous beneficial properties, including its adherence ability, stiffness and strength, as examples. The silicone tape material may be used to display numerous different items, such as those mentioned above, on substantially non-ferromagnetic surfaces, with only a few of the numerous possible items being illustrated in  FIG. 3  as examples. 
         [0025]    While the disclosure has been illustrated and described in detail in the drawings and foregoing description, the same is to be considered as illustrative and not restrictive in character, it being understood that only the preferred embodiment has been shown and described and that all changes and modifications that come within the spirit of the disclosure are desired to be protected.
