Two Blank Monte

One card is then brought to the front - with only the back of the card showing. The spectator is asked to guess which card is behind the magcians back. Their answer is shown to be correct. This is repeated several times and the spectator is always correct! The odds of this are incredibile. For the grand finale one of the cards vanishes. Where did it go? It is stuck to the spectators back.
Comes with re-useable dry erase cards.
