ALEXANDER POKRYSHKIN (1913-1985) Soviet flying ace and Marshal of the Soviet Air Force, he nearly single-handedly updated obsolete Soviet tactics to counter the threat of the Luftwaffe. Typed D.S. in Cyrillic, 2pp. 4to., [Kiev], Sep. 22, 1959, the final leaf from a military attestation for an unknown individual. Pokryshkin signs at the conclusion of the second page in blue ink. Ragged left edge, cutting off the very end of Pokryshkin’s signature, else very good.
