The placement system used in this Karl Fulves trick (which originally appeared as “Stopped Twice” in his Impromptu Opener, 1979, p. 2) may have been adopted from either of two sources: Theodore Annemann's “Locatrik” in The Jinx, No. 39, Dec. 1937, p. 262; or Herb Rungie's “Hidden Mystery” in The Jinx, No. 83, Mar. 1940, p. 535.

Other precursors are Ron Wohl's “Australian Sixes” in Harry Lorayne's Reputation-Makers, 1971, p. 164, and Ed Marlo's “Ruse Cull” in Kabbala, Vol. 1 No. 9, May 1972, p. 74.
