American World War I ace (1879-1936) regarded as the father of the US Air Force, whose zealous ambition and vocal criticism of the War and Navy departments following the war led to a court-martial and his resignation. Vintage matte-finish 10 x 12.75 portrait of Mitchell wearing his decorated military uniform, signed and inscribed in fountain pen, "To my friend Gould Dietz, with the best regards of, Bill. Mitchell.” In fine condition, with creasing and a small tape-repaired tear to the right edge. Mitchell remains rare in signed photos of this size—an impressive and desirable pose.
