Airfare of to-day and of the future
A 1918 New York edition of Edgar C. Middleton's account of military aviation, published by Charles Scribner's Sons for a wartime general readership. Illustrations mix halftone photographs of biplanes on grass fields with stark black silhouettes of aircraft, dashed arrow diagrams of attack angles, and a line map of rivers, roads and rail lines converging on a hatched town.
