A sex tape featuring late screen siren Marilyn Monroe performing oral sex on an unidentified male has been sold to a New York City businessman for $1.5 million, the New York Post reports.

“You see instantly that it’s Marilyn Monroe – she has the famous mole. She’s smiling, she’s very charming, she’s very radiant, but she’s known for being radiant,” he said. “She moves away, and then it [the footage] stops.”

The tape, which appears to have been shot in the 1950s, is a copy of a sex tape obtained by the Federal Bureau of Investigation from an informant in the mid-sixties. Then-FBI boss J. Edgar Hoover sent agents on a fruitless attempt to prove that the featured male was either John F. Kennedy or Robert Kennedy.

Marilyn’s ex-husband, baseball legend Joe DiMaggio, once offered an informant $25,000 for the tape.

The silent black-and-white flick shows Monroe on her knees in front of a man whose face is just out of the shot. He never moves into the shot, indicating that he knew the camera was there, but Monroe never looks at the lens, according to the Post story.

“He said he’s just going to lock it up. He said, ‘I’m not going to make a Paris Hilton out of her. I’m not going to sell it, out of respect.’ “
