ALS signed "Houdini," one page on two adjoining sheets, 8.75 x 11.25, August 2, 1900. Letter to fellow magician Servais Le Roy. In part: "Opened here last night & made good. You ought to see the Handcuffs & irons used in Germany. Here cuffs are used and every station has different cuffs, in fact there are no two alike. I am going to bring some styles back with me & I'll give you a fine pair. Here is the way they look [sketch of the handcuffs]. Has two spring lock & looks like the lilly iron the leg irons look like this [sketch]. Did you know I patented the Hand cuff act in Europe, the drawings won't be published in 9 months. Robinson patented his catching gold fish in the air, and he stopped Hiam from making the trick and Maskeleyne from doing it. The opposition house hired a man from Berlin to expose Hand cuffs & he was closed after his first show. It seems strange people like to see the act exposed. But it does not pay to expose anything." In very good to fine condition, with chipping along one edge affecting one word of text, and minor splitting along intersecting folds.Houdini writes during the first year of his tour through Europe, where he would remain for four years. As he alludes to in this letter, he challenged the local police departments of each city he visited to restrain him; Houdini, of course, inevitably escaped and he became famous throughout Europe as the 'King of Handcuffs.' In addition to discussing his own act, Houdini touches upon the flourishing illusionist trade, mentioning William Robinson, who performed under the name Chung Ling Soo, and John Nevil Maskelyne, known for his levitation illusion. An early, truly remarkable Houdini letter boasting ideal magical content.Format: ALS
