Lecture on the Rhon soaring flight competition, 1921
A 1922 NASA Technical Reports Server record of a lecture on the 1921 Rhön soaring flight competition, a technical report in German aviation circles compiled for engineers and aviation researchers. The two pages are photographic plates of gliders and monoplanes with captions naming each machine, pilot, and club, such as the Blue Mouse, Black Devil, and Espenlaub designs. A designer could take from them the stark, high-contrast look of early aircraft silhouettes shot against open fields and hangars, with grainy halftone texture and small caption typography.
