A 1907 manual training textbook on cardboard construction, written by John Herman Trybom with Ellen Frances O'Connor and Abbie Ellen Wilson, published in Springfield, Massachusetts and New York by M. Bradley Co. for school pupils learning paper work. The pictures are plain line diagrams of flat cardboard nets with dashed fold lines, dimension labels and rulers, plus one small shaded pyramid sketch, useful to a designer for technical drawing, folding patterns and simple geometric construction.
