ABSTRACT:
A frame construction comprising a plurality of frame members secured together to form a geometric shape, preferably a rectangle. The frame is particularly adapted for framing art work, posters, diplomas, etc. Each frame member has a channel formed in the rear side thereof, and the corners of each member are angled. Two adjacent corners are held in an abutting relationship along the angled corners, to form a complementary angle, such as a 90 degree angle. The frame members are held together by connectors, with each connector having a pair of legs, with one of each legs being received in the channel of one of the frame members. The legs include pointed protuberances that are forced into the walls of the channels to securely hold the frame members together.
