Time-Sign by Jason Smith
Take them on a journey backwards in time! 

They pick a card and sign it. Now, without any switches, you really tear up their signed card. They can still see their signature on all of the torn pieces throughout the tearing. You then instantly restore their card and yes, their signature is on their card! 

Brand new method. 

The ultimate torn and restored card!
