Interesting photo of Clarence Chamberlin, a major aviator of the early 20th. century, and competitor of Charles Lindbergh. Not in the best of condition, creases in upper left along with a 1” x 1/4” loss of surface, slight damage to lower left corner, a tack hole upper center, slight tear under the signature, and some adhesive in upper right corner. The AMOCO logo is inked out on the fuselage. Inscribed to his friend, possibly Edsel Ford, signed with Chamberlin only. Photo measures 6 1/2” x 8 1/2”. Interesting piece of American aviation memorabilia. Thanks for looking!
