This palm was published by Ed Marlo in The Cardician, 1953, p. 55. Stanley Collins also wrote up the palm in his “Zeta Four Ace Trick” from Gems of Personal Prestidigitation , p. 24. This book was never actually published, and didn't see the light of day until inclusion in Edwin Dawes's Stanley Collins: Conjurer, Collector, and Iconoclast, 2002.
