 More than half a century later it was purchased by the German Chamber of Industry and Commerce and presented to Adolf Hitler on the occasion of the Führer's fiftieth birthday (20 April 1939).During the latter stages of the war Hitler kept it with him in his bunker at Berlin.It was destroyed (along with the autograph scores of Die Feen, Das Liebesverbot and Rienzi, and the fair copy of Die Walküre) shortly before the fall of Berlin in May 1945 (though a number of conspiracy theories continue to claim otherwise).
