Abstract

A novel construction toy includes at least one substantially planar sheet containing a printed pattern on its surface; a plurality of colored interstacking blocks capable of intercoupling, such as frictionally interlocking, with one another to form a pattern corresponding to the pattern printed on said sheet; an elongate grid block capable of intercoupling with said blocks, and a support structure for holding said grid block and said pattern sheet with the latter in a position underlying said grid block; which support structure includes a first elongated member containing a first planar surface and a second planar surface recessed from said first to define a ledge; means for mounting the grid block in a position on said first member so as to protrude into a position overlying said second recessed surface and thereby define a channel for receiving an edge of the sheet; and a second member coupled to said first member for holding the sheet member from said other end; whereby said intercoupling blocks may be built up upon said grid block to the pattern depicted on said underlying sheet.
