A deck of cards is shown blank on both sides.


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!.


Finally 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!
