John Bannon - Duplicity

A magic four , three effects , triple shock. Choose brand stand , the election card is only a stack of cards color is not the same brand , the unselected cards are blank cards .
The effect is very good .

The basic effect of Duplicity is that a red-backed Ace from one packet changes places with a blue-backed Ace in another packet. The selected Aces appear face-up in each respective packet. Then their backs prove to be different. As a final climax, all of the other cards are shown to be blank. Everything is examinable. Based on Bannon's incredibly popular "Twisted Sisters" routine now streamlined so it no longer uses any gimmicks.
Bonus: Includes the performance and explanation of Party Of One packet effect!
