Thinka-Card (ungimmicked version) by Marc Oberon
Item Number: TA9276
A deck of cards is spread in front of an audience member's eyes as you turn your head. They merely think of any card and you close the spread. You then spread the cards in front of their eyes again, this time apparently watching for clues as to where they look. At this point, you are able to divine the thought-of card, and instantly repeat the effect!
