Two Card Mystery (4170)

This visually, stunning trick will fool virtually every magician who sees it performed! Not just another card trick…this is a visible transformation!
Two cards-blank on one side, a back and a face on the other. The cards are turned over and it is shown that a back design has appeared on one of the cards. The other card sweeps across it and the back design visibly vanishes…they clearly see it happen! Finally, the back is magically, permanently printed onto the card and both are handed out.

No switches. Uses only two cards.
