Rapport officiel sur la première exposition internationale de locomotion aérienne
Official report on the first international air locomotion exhibition, held in Paris in 1909 and published there in 1910 by the Librairie Aéronautique for the aviation trade and engineers. Halftone photographs show aero engines on trestles, radial cylinder blocks, and biplanes in hall displays, alongside lettered line sections through V-cylinders; useful for machined forms, gear trains, and exhibition-stand settings.
