Abstract
Abstract An inexpensive collapsible picture frame is formed from a single blank of cardboard and includes two adjacent panels, one of which has a cut-out window between which a picture may be inserted; the other of these panels having a lock slot cut therein and a glue tab assembly. A support panel having tapered sides is folded rearwardly from one edge of the panel having the cut-out window to permit the frame to be oriented on a surface in either a horizontal or vertical viewing format, and an easel brace panel folds from the end of the support panel toward the two adjacent panels and has a lock tongue engageable in the lock slot to retain the frame in assembled condition wherein the two adjacent picture receiving panels are bowed into a convex shape to aid in frictionally retaining the picture and to reduce glare in use.
