ABSTRACT:
A window envelope 10 for a card file having a pair of parallel bottom guide rails includes a back panel 11 and a pair of front panels 12 and 13 formed of transparent resin sheet material and joined together to form a pair of laterally adjacent pockets for storing viewable objects. Seams along the top 21, the lateral sides 22 and 23, and a lower line 24 extending between lateral sides 22 and 23 close three sides of each pocket, and the pocket openings are along a central vertical gap where the edges 32 and 33 of the front panels are spaced apart. Notches 25 in bottom region 26 allow the envelopes to be mounted and leafed in guide rail card holders for filing 35 millimeter slide mounts 15, coins 16, stamps, and other thin objects.
