The Invisible Card by Dirk Ferguson and Roberto Giobbi

Card College 3 by Roberto Giobbi
Page 523 et seq.

Personal Comment: Creator of the base of this trick is magician Dirk Ferguson who called it Wow! Confusing? I added this fairly known trick to show how weird proper crediting can go. Dirk Ferguson published this under his pen name Richard Bruce in the 1951 issue of Hugard's Magic Monthly (Vol. IX, No. 4, page 835 et seq.) It was an instant hit. For some reason it got also known as the "Biddle Trick" mostly because of some bad marketing by one of those magic companies that sound close to "illusionist". "Wow" however was the correct title. Nowadays "Wow" is often associated with a plastic gimmick. The title that Roberto Giobbi chose is taken as well. Gerald Deutsch's "Invisible Card" comes to mind. Whatever. The world of magic crediting is a difficult one. The trick itself however is a great one. Easy to do, strong effect.

Difficulty 1/5
