The use of the kindergarten gifts
A 1918 kindergarten teaching manual by Grace Fulmer, published by Houghton Mifflin in Boston and New York, for teachers working with children's building gifts. The pictures are numbered isometric line drawings of block assemblages built from rectangular blocks, with their outlines and interior divisions drawn in plain black strokes on a cream ground, which a designer could use as a study in modular construction and axonometric geometry.
