Stills From The Alleged Marilyn Monroe Porno

A newly discovered print of what is purported to be a pornographic film starring an underage Norma Jean Baker (aka Marilyn Monroe) is going up for auction. Here a few stills. Monroe fans insist it's a different woman, but the film's owner says it was shot before the Hollywood sex bomb lost some weight and underwent plastic surgery. What say you?

  Pictures allegedly taken from a newly discovered 8-mm version of a film, purportedly showing Marilyn Monroe having sex when she was still an underage actress known as Norma Jean Baker are shown by Spain's memorabilia collector Mikel Barsa in Buenos Aires, Argentina, Wednesday, July 20, 2011. Barsa plans to auction the film but an expert says the actress in the film is someone else, considerably heavier and less feminine than the legendary film star. (AP Photo/Natacha Pisarenko)
