Aeroplane design : a paper
A technical paper on aeroplane design read by H. P. Folland and printed by the Institution of Aeronautical Engineers in London in 1922, addressed to practising aeronautical engineers. Halftone lantern-slide photographs show wing-spar fittings, bracing-wire anchorages, turnbuckles and strut sockets in close-up, plus small line diagrams of rigging geometry, offering coarse-screen grey plates and hardware silhouettes for collage or diagram work.
