X-FACTOR

By Ron Frost

A selected card is lost in the deck. You remove a four of kind from the deck, which includes the selection. The faces of the cards are clearly shown as the card thought to be the selection is placed on one side.

Employing the "X-Factor", you begin to verify the selections's idenity by sjhowing that the other three cards now have a big black "X" emblazoned on their faces. The mind blowing climax comes when the selection is turned over to show that it not only has a big "X" across it's back , but the back also changed color!
