Marco's Comments:
Interesting booklet dealing with a nice technique: an exchange of a card very magical and very illusive. The booklet comes with a CD-ROM (for PC) with videos of the move and the effects in the book. The effects aren't outstanding, but are good examples of the use of the technique. Also explained a nice colour change, very magical, but with a bad angle.
However, I think that the move is illogical: why to open a fan to insert a card, close it to have the card change? There are more magical and less logically contrived card changes around...
