Apocalypse by Harry Lorayne (and still Richard Kaufman) Volume 1, Number 1 January 1978 Page 1 et seq.
Personal Comment: The very first trick published in the Apocalypse in it's twenty year run. It is a nice trick, although there is no margin of error in this trick, if you mess up, you mess up and there is no out. Not for me. Now 32 years later there are better versions of the effect.
