Marvelous original 11 x 35 broadside poster for the Bradford Empire Theatre in West Yorkshire, July 20, 1913, featuring Houdini's act as the top billing: "The World-Famous Self-Liberator! Houdini: Presenting the Greatest Performance of his strenuous career, liberating himself after being Locked in a Water Torture Cell, (Houdini's own Invention,) whilst standing on his Head, his Ankles Clamped and Locked above in the Centre of the Massive Cover. A Feat which borders on the Supernatural. £200: Houdini offers this sum to anyone proving that it is possible to obtain air in the upside down position in which he releases himself from this Water Filled Torture Cell." The poster features a vivid color illustration of the escape act, showing Houdini upside down in the tank with a monster securing its lid. Professionally linen-backed and restored to near-fine condition. An absolutely breathtaking magic poster, highlighted by the great illustration of one of Houdini's famous tricks.
