The big boxy biplane is one of a fleet of Nieuport-Delage 391 two- or three-passenger airliners flown by French airline Cie Aerienne Francaise (CAF) in the late 1920s/early 1930s. Spanning 34ft 9in (10-59m), they were powered by the seven-cylinder 215 h.p. Armstrong Siddeley Lynx IV aircooled radial engine, had fuselages of Duralumin and wood construction, and the pilot was seated in an open cockpit beneath the upper wing. Although CAF's logo is visible on the fin, no civil registration can be seen. The photo was taken at Vincennes in France during a "baptism" for a CAF service in the Cote d'Ivoire (Ivory Coast) in West Africa, when it was a French colony. The pilot, in the rearmost open cockpit, is being entertained by Cochin-Chinese dancers and musicians, but the precise date is needed.

The photograph depicts the Weymann CTW 200 Autogiro somewhere in France, probably in 1931, with unidentified officers partly obscuring the aircraft. Again, the occasion is unknown, but the design was intended to meet a requirement issued by the French Navy in May 1930. Originally designated the WEL.200 (for Weymann-Lepere), the CTW 200 was an open-cockpit side-by-side two-seater powered by a 95 h.p. Renault 4Pb, and resembled the British Cierva C.19 Mk III. It had dual controls, a four-bladed rotor of 11m (36ft lin) diameter and Bendix brakes. The wings spanned 6-5m (21ft 4in). It first flew, with Juan de la Cierva at the controls, during Easter week 1931.
