A rare original reward poster, 18 x 12.5 in., issued the same day that Reich Protector of Bohemia and Moravia REINHARD HEYDRICH (1904-1942) was mortally wounded by a bomb thrown at his car, offering a 10,000,000 Czech Crown reward for the arrest of the assassins. The document also warns that '...anyone who accommodates the perpetrators...or knows about their location and does not file a complaint, will be shot with their entire family...'. The poster, issued in Prague on May 27, 1942, is printed in both Czech and German and is signed in type by the protectorate's Higher SS and Police Leader Karl Hermann Frank. Folds, otherwise in very good condition with paper still very bright. Heydrich would die of his wounds one week later.
