Fifty lessons in wood working
A manual-training textbook by Arthur Aquila Upham, issued by E. L. Kellogg & Co. of New York and Chicago in 1892 for schoolteachers and boys learning bench woodwork. Numbered line diagrams show joints, laps and mitres in plain outline and axonometric view, with hand-lettered Roman figure numbers and dimension marks useful as spare technical-drawing motifs.
