ABSTRACT:
There is disclosed a picture frame which is fabricated from a single piece of an extruded metallic member which has an "F" shaped cross section. The member is suitably notched at predetermined intervals and bent at scored lines. The opposite ends of the member serve to form a non-continuous corner and are joined and secured together by means of an "L" shaped bracket which coacts with the material of one of the flanges of said F shaped member to rigidly secure the entire assembly. It will be shown pursuant to this invention that only one bracket need be used since each of the other three corners of the frame are integrally formed from said common extruded metallic member.
