ABSTRACT:
An educational puzzle adapted to be assembled to form a predetermined figure including a plurality of substantially flat components each having at least one counterpart edge that is intended to be placed in juxtaposition with a counterpart edge located on another of the components. Each component has a printed portion located along, and associated with each counterpart edge thereof, and the printed portions cooperate to indicate a pair of counterpart edges which are located on separate components and are complementary. The complementary counterpart edges are of suitable shape whereby they are intended to be placed into coextensive engagement to form a predetermined figure or symbol.
