Arkitoy plan book.
Arkitoy plan book is a 1928 construction-toy instruction booklet published by G. B. Lewis Co. for children and home builders, showing how to assemble metal-strip toy models. The pages are line drawings of wagons, trucks, carts, a wheelbarrow, a swing, a merry-go-round and a waiting station, each with a numbered parts list. A designer could take from them the clean, schematic diagram style of early twentieth-century mechanical instruction drawings, with perforated strips and bolted joints rendered in simple outline.
