From The Guardian:
‘Philippe Halsman flew out to Hollywood and photographed Marilyn in her small apartment, as well as doing things around her neighbourhood. LIFE loved the photos and the relatively unknown Monroe was chosen to be on the cover of the 7 April, 1952 issue. This legitimised her appeal and star status, allowing her to sign a multi-year film contract. This image is an outtake from the famous shoot, which was a turning point in her career.’
