Fast magic- and totally amazing!
Ask your spectator to name his/her favorite Queen card. Remove the cards from the wallet, and spread them out with the backs showing. One of the four cards is seen to be reversed face up, and it is the Queen named by the spectator. When it is turned over, it is found to have a different colored back than the other cards! Finally the other three cards are turned over and found to be- all blank! Incredible! Best of all, this miracle can be quickly repeated, and it makes no difference what card is named!
