A home movie showing Marilyn Monroe smoking what appears to be marijuana is set to go on sale.
The never-before-seen silent film, recorded by Monroe's pal at a party in New Jersey in the late 1950s, was tracked down by collector Keya Morgan, who paid $275,000 (£172,000) for the footage.
The Some Like it Hot star is shown puffing on the joint, laughing and drinking wine.
The woman who shot the four-minute clip has asked to remain anonymous, only revealing her first name as Gretchen, but has confirmed the cigarette contained marijuana, explaining, "I got (the pot). It was mine. It was just passed around. It was not a party. It was just a get-together. You know, come over and hang out."
Morgan plans to put the film on internet auction website eBay later this week (ends06Dec09).
He says, "This is the late '50s so she is already very famous, but this is a personal side of her we've never seen before. People have never seen her in such a relaxed pose.
