This is "Diminishing Returns" from Tenyo's World's Greatest Magic series. It is a discontinued item and is believed to be very valuable. How about it for Tenyo fans, collectors, magicians, etc.? [Product Details (excerpt)] A spectator selects a card from a face-up deck of cards. When the remaining cards are spread out on the table, all the cards except the selected card suddenly shrink to half their size! Furthermore, the size is reversed this time! Only the selected card becomes a miniature card, and the other cards return to normal size. Then, the spectator's shrunk card returns to its original size before their very eyes. This is a miraculous magic that has fascinated magicians around the world. It is arguably the most visual and shocking of all card tricks. The inventor, Mike Powers, performed this magic at the Magic Castle, Hollywood's hall of fame for magic, and entertained many people. With this card magic, which is based on an outlandish phenomenon and a well-thought-out gimmick, you can also entertain your friends. Devised by: Mike Powers
