Manual of cardboard construction for third, fourth, and fifth grades
A teacher's manual of cardboard construction written by Charles A. Kunou and issued by the Los Angeles City Public Schools in 1902 for third, fourth, and fifth grade classroom handwork. The plates are flat cutting-and-folding patterns drawn in fine line: solid cut lines, dashed fold lines, dotted centerlines, inch dimensions with arrowheads and letter keys, giving designers geometric net diagrams, measured rules, and dashed-line grids.
