Signed Card to Box

A signed card appears inside a box amongst impossibly set conditions.Not only do the audience know beforehand, exactly what you are attempting to do, but they have surrounded you and signed the playing card.Yet, with all these set in motion, you push their card flush in the deck, make a magical gesture, and clearly show your hand empty, with fingers wide apart, as you pick up the card case with your fingertips, and remove their signed card.No Palming needed
