Finding new and interesting revelations for chosen playing cards is a challenge to be overcome by magicians far and wide.

Using only a borrowed bill and a cell phone, you can seemingly show a chosen playing card imbedded in the fabric of the bill itself.
It's a revelation in an impossible location, taken to the street and then to another level altogether.
