[QUOTE=Hans Pearson;121271]It is a Boeing 337 Stratocruiser. The lower deck was also used as a lounge/bar for passengers. The first 337 flew on 8 July 1947 and production continued until 1 February 1950. In all, about 55 were built and the aircraft was a hybred using the wings and tail unit from the Boeing B-29 Super Fortress. The aircraft had a rather bad name as the steel formed propellers used on some models were inclined to shed blades with severe consequences. Main customers were PanAm, United Air Lines, Northwest Air Lines, American Overseas Air Lines and BOAC.
This photo was probably a promotional shot with air hostesses from the first customer airlines and would have been taken prior to completion of the first aircraft.
