A deck of cards is shown blank on both sides and the magician talks about how cards are printed – not by printing presses, but by magic. At the magicians command, a card appears – but it only has a face but no back. Then the magician “prints” a back but no face. Then the magician shows what a deck looks like that a magician has completely printed by making all the cards have both faces and backs. But a magician can always control the printing on the cards and with the snap of a finger they all turn blank again
