Recovery is the easiest and most practical (yet very deceptive!) piece-by-piece Torn and Restored Card Routine you will come across.
A card is signed on both sides - it's signed on the face by the spectator and on the back by the performer. Then it is clearly ripped into four separate pieces - the spectators can see and hear their signed card being torn.
Now you magically restore their signed card piece by piece. The best part: You can restore the last, signed piece in the spectator's own hand and you end completely clean!
Recovery is designed with the worker in mind: It is angle proof, very clean, engaging, and it resets instantly.
