Treasury by Derek Ostovani
"Derek has cloaked a nice find-a-card trick with a miracle revelation no one sees coming. He's also made the preparation dead simple so no excuses on not having this ready to go at your next gig!" - Doug Brewer
Transform the ink on a borrowed dollar bill. This one is a reputation maker that leaves your audience with an impossible souvenir they will talk about for the rest of their life.
The Treasury gimmick allows you to replace the signature of the Secretary of the Treasury with a playing card on any dollar bill. You can use this for a visual reveal, a prediction, or even a thought of card mentalism effect.
Effects where the ink on a bill have always been tedious to set up, and required special knowledge of using a printer. The Treasury gimmick makes changing that signature a simple process for one of the most memorable effects you can do with a dollar bill.
