Yes, this is a card trick. But what a card trick! One of the best-selling, most popular card tricks of all time! B'Wave has baffled princesses and presidents, and is used by professionals throughout the world. Four cards supply three stunning punches! Max Maven created a sensation when he released his original B'Wave. Practically every magician on the planet owns one, carries it and uses it. Since that time many have created variations, but this classic version has stood the test of time and is still the best. You display four jumbo blue-backed cards (said to be four queens). A spectator selects one of the queens. The named queen is shown to be the only one that is face up. It is also the only one with a red back. To everyone's amazement, the other three cards are then shown to be blank. No sleights, no rough & smooth, no extra cards, just pure mind-boggling magic! The cards supplied are the traditional jumbo size and are suitable for both close-up and stage. Great for emcees, mentalists, magicians, children's entertainers, well just about everyone! Comes complete with four specially constructed Cheetah Back Jumbo (7" x 4.5") cards and illustrated instructions. Can be learned in seconds. No sleight-of-hand required. Self-working.
