Abstract: A device constructed of prefabricated materials which can be used for display of merchandise and/or printed materials in stores, malls and the like. Modular construction permits tailoring the size of the display according to individual needs. In one embodiment of the device, pairs of uprights are attached by means of a novel retainer clip which allows the insertion of a panel between the upright pairs. The resulting structure is extremely rigid, yet can easily be assembled and disassembled without the services of a carpenter.
