Abstract
A system of interlocking keyed play pieces is adapted for receiving and displaying indicia bearing tile members. Each of the play pieces is provided with a display window through which the tiles may be viewed. The pieces may be interconnected both laterally and longitudinally to enable a child to interconnect the play pieces in an infinite number of combinations so as to form a multitude of structures of varying configurations.
