Period original 10x7" b&w photo with typed text on reverse: "No. 3 Maj Frederick L. Martin at left and world flight personnel". Appears to be a congratulatory celebration for the Chicago, one of two Douglas World Cruisers to successfully fly around-the-world in 1924. I believe the pilot with the helmet and goggles is Lowell Smith, pilot of the Chicago. Very good; upper and lower right margin chips. This may well be an unpublished original and thus quite rare.
