The theory & practice of aeroplane design
An aeronautical engineering textbook by Sydney T. G. Andrews and Sydney F. Benson, published in New York by E. P. Dutton in 1920 for aircraft designers and engineering students. Plates run to line graphs of drag, yawing angle and pressure distribution, gridded chart panels comparing upper and lower wing sections, and blocks of matrix and differential notation set in letterpress, useful as technical diagram texture.
