Princess Card Trick.
The performer shows a fan of five cards and asks the spectator to think of one of them. Turning the faces of the cards towards himself the performer gazes at them then removes one, which he puts under his arm. The faces of the four cards remaining are shown.
It is seen that the very card being thought of by the spectator has been removed. Line three people up and do the trick three times. Line six people up and do the trick six times. Sure fire and self-working; no skill required.
This effect was performed on the David Letterman show.
