U.S.S. Macon (ZRS-5) Main Frame Positioned - 1931

Original 8x10" b&w press photo of David S. Ingalls, Asst Sec of Navy for Aeronautics (left) and Fred M. Harpham, VP of Goodyear, giving the command to put the Macon main frame into place. Acme Photo press release (lengthy) and rubber stamp on the reverse. Interestingly, Ingalls is also the only USN WWI ace. Very good.
