German Luftwaffe pilot (1919–1942), nicknamed the “Star of Africa,” who was Germany’s most effective ace during World War II, on one occasion achieving eight victories in ten minutes. Killed during a plane accident, his tombstone bears a one-word epitaph: “Undefeated.” Scarce ALS in German, one page both sides, 8 x 11, July 31, 1939. Marseille writes to his mother. In part (translated): “Today I should have flown to Berlin, but the forest in Thuringen was cloudy. I couldn’t get the wireless operator, so I should have flown ‘blind.’ Therefore I flew to Breslau…. I will try to get some days off on Saturday and Sunday, but I cannot promise…. I received your letter with cash. When I come home I just want to see laughing people.” In fine condition, with usual mailing folds and a few mild scattered wrinkles. COA John Reznikoff/PSA/DNA and R&R COA.
