A picture frame comprises a series of abutting frame elements joined by corner pieces. Each of the frame elements includes an aperture into which the artwork and accompanying materials, such as cover glass, mats and the like are received. Flexible arms extend along the frame elements and are biased to retain the artwork within the aperture, and permits the effective retention of artwork of various thicknesses. The corner pieces include pair projections which engage complimentary bores in the frame elements to retain the frame elements in position. A pair of the cover pieces may be of a modified construction to allow removal of a frame elements after assembly to permit changing the artwork. In such embodiment, a single projection, rather than a pair of projections is utilized to engage the removable frame element.
