As everyone who visits my site should know, I'm a great fan of Rob Bromley's. His tricks are both fantastic in effect and very well made, the card through card has been a favourite of mine for a long time. A deck of cards are shown both front and back and a card is selected and signed by a spectator. This card is placed face down onto the table. The performer himself now selects a card. The performer now pushes his card right through the spectator's card (it looks like it's melting through) as the performers card goes through, it takes on the appearance of the spectator's card including the signature i.e. the two cards change places! This is a very well made gimmicked card that does all the work for you.
