Barbara Stanwyck. I love her hair here. This may be a promotional still for the film Golden Boy (1939) in which she plays a wife of a boxer.
Vivian Leigh in Caesar and Cleopatra, 1945. This whole look is incredible.
The gorgeous Chinese-American actress, Anna May Wong. This photo is probably from the 1930's.
The always influential Louise Brooks, above and below. Both are stills from G.W. Pabst's silent film, Die Buchse der Pandora (Pandora's Box), 1929.
