WAGNER, RICHARD. Autograph letter signed ("Richard Wagner") to Marshall von Biebensheim, Zurich, 18 May 1851. 1 page, 8vo, integral address leaf in Wagner's hand, a few light stains, in German. THE EXILED WAGNER READ'S "SIEGFRIED'D DEATH.": Wagner invites Biebensheim and a friend to attend a reading of "'Siegfried's Tod.'"
