Wunder lumbermanual.
Wunder Lumbermanual is a 1930 instruction booklet from the Wunder Mfg. Co. for children building toys from Wunder lumber, a set of small wooden strips. The pages are dense photographic plates of finished models, each labelled with its name and dimensions. A designer could take from them the modular wooden-stick construction look, the stark black backdrop, and the flat catalogue layout of grid-arranged objects.
