The magician gives a spectator two playing cards, one of them has a few words printed on it and the other is what he calls a "window card" which has a red "decoding" filter. The magician tells the spectator that the prediction card is very much like the predictions made by Nostradamus and that the words don't mean very much until it’s compared to an event that has recently happened. The spectator then shuffles a regular deck of cards and selects one. When the spectator looks at the prediction card through the red window, it now displays the name of a playing card. When the spectator turns over his selection, it exactly matches! Includes two different prediction cards, decoder card, gimmick and complete instructions.
