Display the cards in a fan and show the faces as in a standard deck. Fan again and the faces have vanished; just white paste-boards!. Now the faces reappear.
Next show the backs and each time you fan the deck, the color design changes. Once again you show the fronts and now the faces have changed to a weird series of colors. Fan again and something begins to take shape. Finally fan and the design of a fire-breathing dragon appears on the whole surface of your card fan!
These cards require fanning powder.
