Abstract
A pictorial display resides in the combination of a transparent polyhedron and an opaque backing. The backing is removably attached to the polyhedron block by interlocking elements formed on the backing co-acting with recesses formed in appropriate surfaces of the polyhedron block. Pictures placed between the block and backing are dramatically viewed through the block.
