Kellar, Harry (Heinrich Keller). Kellar ALS to Houdini Regarding Magical Rope Ties and Escapes. Dated July 9, 1921 and written in Kellar?s hand on his lithographed letterhead, thanking his friend Houdini, writing, in part, ?I?appreciate the fact that you have ordered your rope book dedicated to me. It is such acts of kindness that you are always doing that make you one of the best loved of men in our profession. I shall be indeed glad to get a copy of your Rope Book?? Handsomely framed. Sold together with a first edition copy of Houdini?s book, in very good condition. Kellar and Houdini were fast friends and frequent correspondents, the elder dean playing a mentor-like role to the younger Houdini. Unfortunately, Kellar would not live to see a finished copy of his friend?s book; he died on March 10, 1922. As a memorial to his Kellar, Houdini ordered slips be tipped-in to each copy of the publication as a memorial to his deceased friend.
