The Torn and Restored Card

A spectator chooses a card (a completely free choice) and signs the entire face. Their selection is then clearly torn into four pieces and each piece is individually shown. All four are then stacked one on top of another and held at the fingertips. The magician snaps his fingers and opens up the now completely restored card!

Sumit Dua's Remnant features a very fair and real-looking tearing process and a visual, flash restoration of the card and, the best part is that it's not hard to do!
