This Jack Dempsey autograph is a must-have for any boxing or movie memorabilia collector. Known as a champion boxer, he also had credits for 24 movies from 1920 to 1962. The signature is authentic. The original owner worked at one of the major movie studios in the Business Office in the late 1930's and during the war.  She met many of the celebrities when they came in to conduct business or pick up a check.  I came into possession when her husband, a long-time family friend, died and passed on many of her belongings.  I am not an autograph collector, so I leave the value up to you to bid accordingly.
