This is a vintage (1976) effect we picked up from an old magician’s estate. It is complete with all the required red-backed bridge-size cards, plastic wallet, and original Repro 71 instructions.
Effect: A Queen and two indifferent cards are clearly and separately shown front and back. A cute routine follows where the Queen jumps around and reverses. Finally the Queen is removed from the packet and pushed length-wise, face-up through the side of the packet. As it goes through it visibly changes to an indifferent spot card!
