We picked this up from an old magician’s estate. It comes with the original instructions and special pip moving jumbo card.
EFFECT: Performer has a spectator select a card, look at it, replace it into the deck, and shuffle it. Performer then explains that prior to the show he chose a prediction card from his own deck, a jumbo deck, so that there would no chance of getting the two cards confused.
He states that his “prediction” card will match the one selected by the spectator. But upon examining the card, he finds he’s wrong.
But no problem, the performer instantly and visibly changes his prediction card to the selected card!
The spectators see an extra pip appear and move downwards to the center of the card changing the two into a three!
