The Mauboussin M 11 touring airplane (French) : a two-place high-wing monoplane
This is a 1931 NACA aircraft circular issued by the National Advisory Committee for Aeronautics, documenting the French Mauboussin M-11 two-place high-wing touring monoplane through photographs for engineers and aviation researchers. The page shows three photographs of the aircraft, numbered figures 2, 3 and 4, taken on grass airfields from different angles. A designer might take the strong clean silhouettes of the wings, struts and fuselage as reference for vintage aircraft form.
