You picked up a drawing, open one page, draw poker points, told the audience that this is your prediction, and the audience chosen card is same with you.
But when you put the drawing show to the audience,that is wrong, the card is completely different!
You said not to draw the wrong, but is not complete. So you have painted a few, to take the frame, a card box.
You put this on side, in the absence of any contact, card box painted suddenly rose slowly out of a playing card, the card is exactly same with the audience chose !
Then the paper can be torn down and give the audience as a souvenir.
Easy to carry, and easy to prepare, at any time to play, rare good programmes!!
