The magician places two cards aside on the table. Two others are chosen by the public and all this will give life to a succession of amazing effects.
The cards chosen by the spectators will have the same back as those of the magician.
Turning them facing, they will be perfectly matched in value and color with those of the performer.
Finally, the whole deck is shown face up and it will be seen that they are all the same and red: the cards chosen are the only ones that are black!
