Description
A deck of cards is shown on both sides. They are blank on both sides. The cards can be shown individually. Suddenly all the cards have both front and back. Make the spectators believe that you thoughtfully changed the cards from blank to having both fronts and backs.
It may not look like much in print, but it’s visually stunning and surprising to the audience. It’s one of the most amazing card tricks ever.
The cards are Poker size.
