Pop-Eyed Eye-Popper Deck  

AKA  Nu-Idea Forcing Deck

The Pop Eyed Popper Deck  is a forcing deck marketed  by Ralph W. Hull  around 1942.

This deck of cards is similar to the Svengali Deck,  except the Pop Eyed Popper Deck allows the performer to spread the cards face up, showing all the faces of the cards to be different, then turn the deck face down and offer a spectator to touch the back of ANY Card . The card they touch will ultimately (and always) be the force card. This deck can be used in conjunction with many other routines that require you to ultimately know the card before it is selected.
