But it was a moment after Monroe sang at Madison Square Garden in honor of the president's 45th birthday that is attracting attention. In the photo Monroe, wearing the same dress she performed in, is speaking to President Kennedy, whose head is tilted slightly and looking down while listening to her. His brother, Robert Kennedy, is standing next to the pair looking on. The photo was snapped at a private party at the Manhattan home of Arthur and Mathilde Krim, according to filmmaker Keya Morgan who owns the print. He said the existence of the image was kept a secret for decades.
