A rare look at Marilyn Monroe

This photo was taken on the set of "The River of No Return." It's never been seen at all, in fact it wasn't even included in the auction in which Limited Runs acquired these images. It was acquired from the Allan "Whitey" Snyder estate after the auction.

Limited Runs is hosting a traveling exhibition of rare, never-before-published Marilyn Monroe photographs.

The show launches June 6 and will travel from Los Angeles, to San Francisco, to New York throughout summer 2014. Click through to see some of the shots.

Marilyn Monroe, 1953

This was taken during the filming of "River of No Return." It was early morning and Monroe and Snyder were on their way to hair and makeup on set. They came across some baby black bears and Snyder snapped a photo of it. It's very rare to see a photo of Monroe without makeup; she almost never let anyone photograph her without it.

Marilyn Monroe, 1956

This was taken on April 15, 1956. Monroe was in the middle of filming "Bus Stop" on a Sunday afternoon. She and photographer Milton H. Greene decided to take some pictures on the back lot of 20th Century Fox, and they had the whole lot to themselves.

Marilyn Monroe, 1952

Mischa Pelz was a commercial photographer, who usually shot products. He and Marilyn were friends but had never worked together until he was hired to shoot the lawn furniture with her as the model. This was taken right before the film "Gentlemen Prefer Blondes."

Marilyn Monroe, 1952

This photo was taken during the filming of the movie "Niagara," in upstate New York. There were no other photographers around, it was only Snyder and Marilyn taking pictures in between takes as a way to relax.

This was shot on location during the filming of "Bus Stop."

Marilyn Monroe, 1952

Lani Carlson was a sound engineer working for Capitol Records and he did a lot of live events. He and his business partner went to this event to set up the sound, and afterwards he left and came back with his camera and a press pass that his friend working for the Chicago Tribune gave him. He was able to get exclusive access to Monroe for a half hour by claiming he worked for the Chicago Tribune and needed to get the photos onto the AP wire, even though there were about 15 other well-known photographers waiting to take pictures of her. He developed the photos and then they sat in a shoe box until 2010. This photo was taken with a 3D camera.

This photo was also taken by Lani Carlson that same day.

Marilyn Monroe, 1957

This photo was taken in 1957 in England during the filming of "The Prince and the Showgirl." The photo was taken on set during a costume test. The film was being produced by Monroe and photographer Milton Greene. Laurence Olivier was directing the film, but he and Marilyn didn't get along well, so in a lot of the photos from this session she isn't smiling. In most of Snyder's photos, though, she's smiling because of their close relationship.
