Hooker, Dr. Samuel Cox. Invitation to Dr. Hooker's Impossibilities. [New York, 1934]. Blotter-size invitation to the famous Brooklyn address 82 Remsen Street, where Dr. Hooker performed his now-legendary Hooker Card Rise, known at the time as "Impossibilities." Photos – one depicting the floating teddy bear head of Miltiades the III, the other depicting cards in a hanging houlette – flank the text. 9 ¼ x 4". Corners creased, else very good. Scarce. Late in his life, Hooker revived the performances of his famous card rising trick, but, as this invitation states, the tricks were presented by John Mulholland with the assistance of Dr. Shirley L. Quimby. Hooker's health prevented him from performing. The invitation states: "During the coming months opportunities will be given to members of the Society of American Magicians to see a revival of the effects which Dr. Samuel C. Hooker first introduced about twelve years ago." To this day, Hooker's invention remains a closely-kept secret, and his "any card called for" card rise using a borrowed pack has yet to be duplicated by another magician.
