I'll admit that this does look AMAZING and very CONVINCING, but the fact that the card HAS to be torn again for 'examination' really does kill it for me - don't get me wrong, I will pick up a copy myself! It's just that besides the restoration process, the souvenir-aspect of the torn and restored plot is what REALLY sells it... but since the card is torn in half, what's the justification? I did like the "spectator one signs side-A and spectator two signs side-B" that one of the members suggested, but the spectator will just be holding HALF a card (if you know what I'm saying)...
Oh, man. If only it were possible to have a spectator pick a card which you have a duplicate of and switch the cards at the end...
