  • Card storage and display device and method of use
    Patent number: 6442878
    Abstract: A card storage and display device (20) includes a first sheet (22) which is attached to a second sheet (36). A first sheet (22) has a plurality of parallel slits (24) which are arranged in stair step fashion. First sheet (22) also has a corresponding plurality of tabs (32), also arranged in stair step fashion, wherein each slit (24) has an accompanying tab (32). The second sheet (36) has a plurality of openings (38) which align with and accept tabs (32) when first sheet (22) is placed on top of second sheet (36). When a card (500) is inserted in a slit (24), the lower corner (501) of card (500) abuts tab (32) and thus prevents further insertion of card (500) into slit (24). Resultantly, a portion of card (500) remains displayed to a user.
