This is a good one to carry with you all the time. The moment comes to hand out a business card to your prospective client, and you find only one card left in your case. So you tear off a corner and give that to the client, telling them to simply remember its yours when they need a magician. Thinking better of this, you show the rest of card (the torn away space at the corner very visible, and you take back the corner piece and almost visibly (it seems visibly) merge it back together.
How good is this? Well, only one card is used. The card can be signed by the spectator before it is torn, and the spectator can see their signature on the card with no corner. So, yes, it is REALLY good!
Can also be adapted to use bridge size playing card, signed, torn and restored, but why? Use your business card and get more bookings!
This effect is made now by Sterling Magic, and the gimmick is not as deceptive as the originals that Doug Bennett put out in the 1980's and early 1990's. But the illusion is still very strong. You will fool people badly with this, but I just wanted to let you know that it is not quite as well made as the original.
As a bonus, with the new Sterling version, you get a reprint of the 1984 Business Merger Book. So you get extra tips and routines from Michael Ammar, Michael Weber, and the inventor Doug Bennett.
Brand new with instructions and extra book.
