ABSTRACT:
A block set, each block including a generally cubical portion with a frusto-pyramidal or convex portion, and an oppositely disposed frusto-pyramidally configured mating concave portion for interlocking. Each of the fourteen surfaces or sides thus formed includes a substantially similar pictorial depiction of an object, such as an animal or the like, with a letter imprinted on the object, preferably in a portion of the object which bears a resemblance to the letter. The edges of each side of the block are colored, with each edge being a different color for promoting color awareness, with the like colored edges of adjacent blocks establishing a preferred orientation for pictorial and indicia alignment. The individual pictorial representations on adjacent surfaces of the same block are oriented in different orthogonal directions for enabling reading of a word on the adjoined surfaces of adjacent blocks on at least one other of the adjoined surfaces of the blocks. The block may be formed as a unitary member or may be formed from foldable blanks formed from a sheet of foldable cardboard or the like.
