The G31 was a large airliner seating 16 passengers. Only 13 examples were built. The unusual tail configuration here reveals the dual national flags to be carried by German aircraft from 6 July 1933 - the black-white-red flag on the starboard side and the swastika flag on the port side. The swastika flag became the only German flag in September 1935. Photo by: Willem van de Poll / Nationaal Archief (Netherlands)
