53 on a Card by Micha Fritaen
You know that classic effect where you force a card and claim to know the card in advance? Then you open an envelope and reveal a card... with all 52 cards printed in miniature.
This is exactly the same effect but with a twist: you open a huge card that is folded. You show them front and back as you open them.
Finally, spectators see all 52 cards printed on this giant card. Then you turn it over and there is only one card on the back: the card the spectator chose!
With 2 pre-folded giant cards, an envelope and PDF instructions in English.
