Building a full-size glider
A 1927 NASA technical report giving construction instructions for a full-size glider, with figures keyed by number for designers and builders. Its pictures are plain line drawings of wing bracing, strut joints, skid and wheel fittings, and a dimensioned wing section, labelled with materials such as sheet steel, screwood and bracing wire. A designer could borrow their clear, labelled technical-diagram style for mechanical or engineering illustration.
