Once Upon a Time by Wayne Dobson and MagicTao

Description:

The fact that you can “predict” the outcome of the spectator’s shuffled face-up/face-down cards is really amazing. -Danny Orleans, Genii Magazine

You show two spectators a little booklet entitled “Once Upon A Time”. The booklet is put to one side to be referred to later. You hand each spectator half of the pack of cards. Each spectator cuts thsie individual pile of cards into two; turns one of their piles over and then swaps the turned over pile with the other spectator.
