Dragon Fanning Deck
This set of cards published by DP Group Ltd (Japan) was designed for magicians. The deck is a full inch and a half longer than standard poker size decks and has a back design that allows the performer to create different fans. Fanned in one direction the deck appears ordinary. Fanned the other way the cards form a full-colour picture of a menacing dragon!
Several other styles of fanning decks are also produced by DP Group, who specialise in magic and juggling tools, DVDs, etc.
