Ultimate ESP by John Shirley: Jumbo Cards

One of those that is fun to do because you are making the moves right in front of them with a wonderful mechanical stand.

You show a stand with five jumbo ESP prediction cards in back out.  You then show a group of matching ESP cards. The spectator makes the free choice to pair any of the visible cards with the prediction cards.  It is an absolutely free choice.  When the cards are removed they are found to have matched exactly!  the spectator can even remove the cards from the stand if you wish.  A great ingenious effect. 1970’s. Excellent condition.
