You place a stack of printed cards on the table on which your audience can see a playing card in a champagne glass.
However, only the back of the playing card is visible. Now ask your spectator to sign one of these cards, turn it over, and then immediately cover it with their hand.

Now the spectator may choose a playing card from a deck of cards and should concentrate on its value.

After a few seconds, ask him to turn over the signed card. It's hard to believe: But the playing card on the printed card has turned over in the champagne glass and shows exactly the value of the drawn card. The spectator can keep the printed card (which also bears his signature) as a souvenir.

So that you can repeat the trick, we provide you with 60 cards with 3 different values.

The backs of the printed cards are designed like business cards. Here, you can enter your contact information (stamp and address label). Since the spectator can keep the card, you've presented them with your business card in an elegant way.
