Vintage matte-finish 10.5 x 13.5 softly–focused photo of Dempsey in a tuxedo and hat, signed and inscribed in fountain pen “To my friend George Siegmann, The fellow that K. O. Me, Good luck, Jack Dempsey April 10/25.” Dempsey and George Siegmann appeared together in the 1925 silent film, Manhattan Madness. Siegmann’s great–grandson states that his great-grandfather George Siegmann did KO him during filming of the Hollywood Hotel. Jack told George not to worry about pulling a punch during filming so he didn't pull the punch and Jack went down on the staircase. Lightly trimmed edges, a couple slight corner tip creases and a bit of mild silvering, mostly to edges, otherwise fine condition. Steve Grad PSA/DNA and R&R COA.
