Definitive Double Signed Torn Restored Card

A deck of cards is spread out on the table, allowing a spectator to freely choose one. After signing her name on the front, the magician adds his signature to the back. With empty hands, the magician folds the card to weaken it before tearing it into four distinct pieces, each displayed individually. With a simple squeeze, the torn pieces astonishingly restore themselves, creating a stunning visual effect.
