>Check out issue 18 of The Chronicles for "Paradox" by Mitsunobu Matsuyama.
In a separate email, I sent you the pages of the Chronicle issue in which it appears.
The idea was first invented by Masao Atsukawa, then by Yasuo Kiga, as I told to Karl Fulves on pp. 1237-1238.
The Masao Atsukawas original version appeared in the New Magic, September, 1967, and he continued to create several different versions.
The version David Acer talked about would be the finest one.
I wonder what version Paul Daniels performed.
