Phil Goldstein was the first to publish this plot and a method, in which four cards rose to the tops of a packet, then changed color. His trick appeared in his booklet Scattershot, 1977, p. 7 (and later in Focus, 1990, p. 41). However, Bro. John Hamman had come up with the same plot and method in the mid-1960s, according to Richard Kaufman. Hamman's trick, “Double Surprise Elevators,” was published in Genii, Vol. 64 No. 2, Feb. 2001, p. 39.
