This came from an old magician’s estate. Complete with the wallet, gimmick, and original instructions.
EFFECT: Performer shows a small identification purse with celluloid sides. A five dollar bill can be seen under the celluloid on one side of the purse and a one dollar bill on the other side. Performer hands five dollar bill to spectator or places it in spectator’s pocket. The one dollar bill he retains for himself. Upon command the two bills magically change places! Spectator finds he has the one and performer has the five!
Note: You must supply your own bills.
