[Class 132 (iii)] A set of toy building blocks is made of uniform size in the section of a right-angled isosceles triangles, the thickness of each block being equal to the length of one of the two equal sides of the triangle, all the faces of each block being treated to simulate different elements of building construction. Brick, tile, stucco and other building patterns are simulated, e.g. as in Figs. 1 and 4. The blocks may be made of clay or plastics, the design being impressed into the faces during manufacture. Alternatively the blocks may be made of cardboard or similar material printed before being formed into blocks.
