A JUMBO CARD TRICK THAT IS BAFFLING EVEN TO MAGICIANS!
Four jumbo size Aces (or any other four-of-a-kind) are placed face up on the table (and only four cards are used). A spectator is asked to select any one of the cards (no force of any kind). He may mentally change his mind any number of times, but finally he must decide on one card and announce this aloud. When the cards are shown, it is seen that the designated card has a different colored back to the other three!
No sleights whatsoever are used. They are replaced by stunning subtlety.
Complete with jumbo cards and routine. No rough & smooth cards, no double-lifts, no special cards.
