I posted this in another area of the forum but perhaps someone at this site will have some info.
I have this effect and I'm wondering if anyone knows what it's value might be. I'm not sure, but I don't believe these are being made anymore. It's a great mentalism routine using jumbo ESP cards and a wooden card stand. A spectator arranges the cards in any order on the card stand, face down. They are then covered with numbered plaques. The performer stands across the room, back turned, and is then able to identify where each card is located. Any thoughts on this routine or other information would be appreciated.
