At the outset, this trick appears to be fairly standard: The magician has a card selected, signed and lost in the deck. Next, attention is called to a saftey pin running through the magician's tie. Then, things get interesting. The cards are fanned in front of the tie and WAMMO! the signed selection is seen to be pinned to the magician's tie! The card actually has to be ripped off the pin to remove it!
If you don't wear a tie, no problem - the pinned card is instantly and easily adaptable so that the card can appear pinned to a coat, shirt or even t-shirt.
