Abstract
A modular display system is disclosed for displaying a map, graph, chart or other planar graphic representation in a plurality of planar modules capable of being disposed in a planar contiguous array having a smooth, markable surface. Each module is formed of a generally rectangular planar base portion having a plurality of planar projecting tongues and planar grooves, a rectangular portion of a map, graph, chart or other planar graphic representation, and a rectangular planar transparent cover portion. The aligned attachment of a base portion, a graphic portion, and a cover portion using adhesive forms a module. By temporary interlocking planar arrangement of modules, with tongues and grooves of each base portion in mating disposition with the grooves and tongues of other base portions, a planar surface is provided with the graphic portions capable of being viewed through the cover portions.
