"I have always wanted to present a close-up version of Cardiographic but have been unable to create my dream pad until recent advances in material technology made it possible.
"My criteria was simple, I wanted a pad that would comfortably fit in my pocket. That could be done surrounded under the closest scrutiny. It had to be self-contained and needed a fast reset for strolling, and most important of all, it had to look impossible."
- MARTIN LEWIS
With Close-up Cardiographic, Martin has taken his classic sketchpad Rising Card to the next level. The effect is the same as Cardiographic, but built for close-up performances; a drawing of a selected card rises from a drawing of a deck of cards. The resulting impossible object is handed out as a souvenir.
