Abstract
Abstract An educational visual display system for teaching geography in which objects having some geographical or topographical significance, e.g., states of the Union, may be detachably affixed and arranged to demonstrate relationship between the objects. The preferred system includes (1) a primary background surface of iron velvet fabric material to which hook type fasteners may be detachably adhered, (2) a plurality of primary objects having geographical significance and comprising a soft foam core with a layer of iron velvet fabric on one side and a plurality of hook type fasteners on the other side, the primary objects being arrangeable to represent in combination a larger geographical unit, and (3) a plurality of secondary objects each having geographical or topographical significance and having hook type fasteners on one side thereof for being detachably affixable to the layer of iron velvet fabric of the primary objects. The iron velvet fabric and the hook type fasteners function as an attachment pair similar to hook and loop fasteners sold under the tradename VELCRO®.
