Lincoln logs.
This is a 1923 instruction catalogue from John Lloyd Wright Inc. for Lincoln Logs, a building toy of notched miniature timber logs, published for children and home builders. The pages show sepia printed plates of finished model cabins, pig pen, cow shed, bridge, table and chapel built from numbered log sets, each labelled with a set number and model name. A designer could take the plain, diagrammatic layout of numbered parts and captioned models as a model for clear exploded-view product illustration.
