Abstract
An improved poster frame and display holder for replaceable posters and similar advertising material is disclosed. The sides of the frame include sets of interconnected, and preferably pivotably engaged, extruded metal, molded plastic, or other front and back frame members. A spring member biases the front and back members together for releasably holding a poster or similar display. Interlocking portions of, or attachments to, the front or back members substantially prevent relative longitudinal movement therebetween, while still allowing relative pivotal movement therebetween.
