Correctly sized postcard with Hans-Ulrich Rudel. Comes blank, or with his autograph and a canceled postage stamp (with diving Stuka bomber of course!). The cancel is from his home-town Konradswaldau, now Kondratów in Poland. 
 
Greatest bad-ass of the war! 519 Russian tanks destroyed (14 in one day!), never shot down by a plane. World record 2530 combat missions flown. Earned one and only Knight's Cross of the Iron Cross with Golden Oak Leaves, Swords, and Diamonds.
