Aerial age
Aerial Age was an American aviation trade periodical issued in New York by The Aerial Age Company in 1922, written for engineers, manufacturers, and pilots following the industry. Its pages mix hand-lettered engineering diagrams — propeller blade sections with force vectors and angle marks, gridded performance charts of engine and propeller output against speed — with halftone photographs of aircraft and ground structures such as the steel dirigible mooring tower at Lakehurst, useful for technical line work, chart layouts, and period aviation imagery.
