This was one of the most famous performances in American history - Marilyn Monroe's version of "Happy Birthday" to President John F. Kennedy at a democratic fundraiser on May 19, 1962.The only known photo of the two together is revealed.
But it was a moment after Monroe sang at Madison Square Garden in honor of the president's 45th birthday that is attracting attention.
A black and white image, which is now up for sale, is the only known photograph of Kennedy and Monroe together, perhaps because of the rumors of an affair that have swirled for 50 years.
The only known photograph of President John F. Kennedy with Marilyn Monroe is to be released today.

"In fact, they were photographed together many times, but the Secret Service and the FBI confiscated every single photograph."

"The Secret Service came in when he was developing the negatives and basically confiscated all the ones of Jack, Bobby with Marilyn," Morgan said.
"The only one that survived is the one that was in the dryer.
