Manual training--play problems; constructive work for boys and girls based on the play interest
A 1917 American manual training manual by William Samuel Marten, published in New York by the Macmillan Company, offering shop projects for boys and girls built around play interests such as toys and games. The pictures are plain working drawings in line: technical plan views, top and side views, and dimensioned stock lists for sticks, discs, fencing rods and a glider. A designer could borrow the clean, labelled diagram style and the dimension callouts for vintage instructional graphics.
