You display eight cards to the audience which are blank on both sides along with four regular cards, let's say the Kings. A folded handkerchief is also placed on the table. The spectator "sandwiches" each of the Kings between two blank cards. Magically, the Kings also turn completely blank on both sides! To finish, the four Kings appear underneath the handkerchief!
Comes complete with all of the specially-printed cards on Bicycle stock.
