Choose your Queen

A wallet is placed on the table. A spectator is asked to name his/her favorite Queen. The cards are removed from the wallet, and spread backs up. One of the 4 cards is seen to be reversed face up, and it is the Queen named by the spectator. When turned over, it is found to have a different colored back. Finally the other three cards are turned over and found to be blank. 

Complete with vinyl wallet(s), cards and routine.
