American World War I ace (1879–1936). His zealous ambition, overreaching bravado, and vocal criticism of the War and Navy departments following the war led to a court-martial, a guilty verdict, and prior to a suspension, his resignation from the military in 1926. Vintage matte-finish 7.75 x 9.75 photo, signed and inscribed in fountain pen, “To Lieut. Clayton Bissell with the greatest appreciation and regard for his service, Wm. Mitchell, Brig. General, Air Service, 1924.” Neat trimming to blank border and a few creases to background, otherwise fine, clean condition. R&R COA.
