Mechanical drawing problems for high schools, normal schools and vocational schools
A 1918 drafting exercise book by Edward Berg and Emil F. Kronquist, issued by the Manual Arts Press in Peoria, Illinois for high school, normal school and vocational drawing classes. The plates are line-only orthographic and auxiliary-view problems on tinted paper: octagons, cylinders, wedges, center lines, dimension arrows and fractional figures, useful as technical diagram texture or geometric ornament.
