Abstract: A peripheral framing system for mounting and displaying a poster or other sheet material. The framing system requires no rigid backing since the framing elements themselves serve to support the poster or other displayed object. The system is comprised of a base structure, a clamping structure and, if desired, a protective translucent covering. The base structure includes several elongated frame members, each of which extends between a pair of angled ends. The ends of adjacent base frame members join together by means of a mortise and tenon to form a rectangular base frame when assembled. The clamping structure comprises several clamping members, one for each of the frame members, with each of the clamping members having a plurality of pegs. The base frame members, translucent cover, and displayed object each have an equal number of holes to receive the pegs.
