Konstructo building blocks.
A Konstructo Company toy manual from 1918, a set of instructions for building blocks aimed at children, with numbered pages of finished models. The plates show wooden-looking structures such as a picnic stand, garage, dog house, bird house and staircase steps, drawn in fine line with simple shading and labelled beneath each model. A designer could take from them the clean, numbered catalogue layout and the simple, boxy architectural forms of early children's construction toys.
