Abstract: A display device upon which erasable indicia may be written comprises a rigid frame encompassing a planar marking surface and corners joining elements of the frame. The frame comprises an elongated top spaced apart from a parallel, elongated bottom, and a pair of spaced apart sides extending perpendicularly between the top and the bottom. The sides and top are formed from a single continuous piece of aluminum extrusion having a generally J-shaped cross section. A similar extrusion forming the bottom comprises an added outwardly extending tray. The planar marking surface is preferably fiberboard, spray coated with polyurethane. Crimps defined in the frame secure the board. Each upper corner of the device is reinforced by a resilient, snap fit hanging bracket which is offset from the back of the board to engage a fastener. A pair of L-shaped modular corners join the frame sides to the bottom.
