Four red-backed aces and a blue-backed Joker are shown to the audience. The magician clearly places the Joker card into his pocket, but it immediately reappears among the aces! All of a sudden, the backs of all the aces turn blue, while the Joker's back is now red! To finish, all the backs of the cards change again into green, gold and black!
Comes complete with the necessary specially-printed Bicycle cards and illustrated instructions.
