This is an amazing close-up trick. One of Peter's best!
You show four-of-a-kind, say the four Kings, and lay them in a face-down row on the table. Twelve blank-faced cards are shown and a spectator deals three cards onto ANY King (free choice). The spectator deals the remaining nine cards on each remaining King. You pick up each packet in turn and after showing the King you cause it to vanish leaving four blanks. The spectator turns over his freely chosen leader pile to find All Four Kings.
Comes complete with instruction sheet and all necessary cards.
