Bruce Cervon performs a torn-and-restored cigarette paper, which Stuart Cramer attributes to Karl Germain. Nate Leipzig is also often credited with devising this approach to this venerable effect. Both Doug Henning and David Copperfield each performed versions of this effect on their television specials.
This particular handling was developed by Martin Lewis. Martin tells us, "I created 'Undivided' in the early 1970s. Dai Vernon told me about Leipzig performing th effect in a large theatre and that prompted me to create this handling. It was around that time that I shared it with a few friends, including Bruce, but I didn't publish it until 1982 and only then in lecture notes."
