"This is a really nice idea, Tom." - Peter Nardi
This method allows you to remove a signed card from the deck... while the deck is in the box.... and while the box is in your pocket.
The method is easy-peasy, and it does not require a deck switch - thus, you can still use the deck for the rest of your card magic, before and after the "card to impossible location."
Application ideas: - Card to Wallet - Card to Envelope - Card to Shoe - Card to Thought-of-Location
