Clear Thoughtby Peter Duffie ANOTHER WINNER FROM PETER DUFFIE!!!EffectFour cards (say Queens) are placed face up on the table and a spectator thinks of one of them. Four more cards - blank on both sides - are introduced. A spectator chooses one of these cards and now it has changed into a duplicate of the spectator's though-of card. You take the remaining three blank cards and change them into duplicates of the other three Queens! Comes complete with cards and illustrated instructions!
