Here's the legendary blonde bombshell, Marilyn Monroe on the set of the 1954 Otto Preminger film, River of No Return. Monroe's costar on the film was the great Robert Mitchum. Though the movie was set in Northwestern American in 1875 - the script premise was taken heavily from the 1948 Italian film, Bicycle Thieves.
Photographer John Vachon took this shot of Monroe. He worked for many years as a staff photographer for Look Magazine. He first worked as a filing clerk for the Farm Security Administration before being recruited to join a small group of photographers, which included Walker Evans.
Monroe later injured her foot on the set of River of No Return. And Vachon captured shots of her in a swimsuit while on crutches.
