PROMOTION

Remove a normal five dollar bill from your wallet, or even borrow one from a spectator. Have it signed. VISUALLY CHANGE IT INTO A TWENTY DOLLAR BILL! A moment later, hand the just changed twenty out to be examined...THEIR SIGNATURE STILL ACROSS THE BILL!

Promotion is all about heightening the impossibility of the bill change. When you do magic with a perfectly unique (signed) and even borrowed object, it will stick with your audiences for a long time. SIGNATURE STILL ACROSS THE BILL!

Keep in mind:

The bill can be borrowed and signed! (American Currency or any bill that have similar colors)
The gimmick does most of the work for you!
Reuse the same bill after multiple performances!
Immediately examinable!
Takes up minimal pocket space
The DVD includes detailed instructions on making the gimmick and how to use it in performance, as well as materials to construct your own gimmick in minutes.
