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.” ALS in German, signed “Hans Joachim,” one page both sides on lightly-lined graph paper, 8.25 x 11.75, no date. Letter to his parents. In part, “Do you remember the girl who was sitting in my cabin? We chatted nicely and exchanged addresses. She is just wonderful. She has the intention to write to me. Great thing! The journey was nice and entertaining. Tomorrow is the harvest festival and it will be a great booze-up. But don’t worry about me…When will I get the English newspapers, that are hopefully included in the parcel? How is Inge? I hope she entertained herself? I am excellent. It is extremely hot here! Already 32 Celsius at noon in the shade. One spends a lot of money for drinking here.” In fine condition, with a couple light pencil notations, a light shade of toning and slight show-through from text on reverse.
