Wow!  I like this trick so much, because it is visual, uses money (always of interest), it's relatively easy-to-do, and it has a funny and memorable ending, as routined by the great Phil Goldstein.

The effect is sort of like Wild Card for money, where you print blank pieces of paper into real dollar bills.  (Or hundreds if you want to show off, and you can afford it -- the real money is NOT included, but you get everything else you need to do this great trick!)

Magician shows some plastic holders and a few blank pieces of paper.  The holders are shown empty in a very clean way (thanks to Shigeo Takagi's genius), and a blank is putr into one.  A real bill is put into another, and in a flash, the blank paper has printed to be a real bill.  Theis is repeated again.  And the third time, the magi discovers that the paper has a corner torn off (like in the picture).  But he continues anyway, and when the bbill prints itself, it also is missing a corner!

I can't tell you how convincing the corner thing is... I almost fooled myself when I first learned this routine.

This high-quality set of props was put out by Marcelo Contento in 1998.  The one for sale her eis new and still sealed in it's package.  (The pictures are of my own set in my personal magic collection).

The corner routine above is Phil Goldstein's handling of the original Shigeo takagi effect, called Cash Card.  The instructions included explain both!  Two tricks for the price of one!
