A picture frame assembly includes a backing plate having a front surface, a rear surface, and a plurality of parallel grooves in one of the surfaces. The material and thickness of the backing plate are chosen so that the backing plate may be plastically deformed about a bending axis parallel to the grooves. At least one frame element, which may be formed integrally with the backing plate, is for provided for retaining a planar picture element against the front surface of the backing plate. A pair of tack elements extending from the rear surface are provided for mounting the assembly to a cylindrical object such as a tree or a candle.
