Abstract
Abstract A picture frame for photographic snapshots having a rotatable easel of thin, lightweight construction mounted to the back side of the picture frame. The easel has a substantially trapezoidal shape when folded and has rectangular front and back panels having a common top edge and collapsible, triangular side panels interconnecting the front and back panels. The side panels may be folded, collapsing the easel into a flat structure for easy packaging and shipment. The side panels when unfolded form an easel for holding the picture frame in a stable, secure, upright position on a tabletop. The easel design of the invention produces an unusually stable structure for its weight. It does not collapse upon moving the picture frame in any direction on the table surface. The easel may be rotated to permit display of snapshots in either a horizontal or vertical orientation.
