NEUMANN, Oberleutnant Paul. Die internationalen Luftschiffe und Flugdrachen. Ihre Bauart und Eigenschaften nach dem Stande von April 1912. Oldenburg, Gerhard Stalling, [1912].
4to. Original blue cloth, lettered in white; pp. [4, illustrated advertisements], x, 209, [6, illustrated advertisements], illustrations in the text, folding tables (one foxed) large fold-out plates after photographs, head and tail of spine a little worn, otherwise very good.
Very rare. Substantially enlarged second edition (the first edition of 1910 had only 102 pages), the last before the Great War, which changed aviation technology fundamentally. This rare work sums up the achievements of aviation design, with some almost forgotten types of aircraft.
