The original of the trick in which a spectator tries and fails to place a paper clip onto the center card of a glued array of cards while it is face down was devised by G. W. Hunter: It was marketed as “Wrong Again!” by Will Goldston, who touted it in Goldston's Magazine of Magic, Vol. 4, No. 5, October 1916, p. 69. His ad for it appeared in the Sept. 1916 issue of The Magic Wand, Vol. 7, No. 1, p. 35. Joe Stuthard marketed an improved version called “Klip-Trick Monte” in April 1950 (see ads in Genii, Vol. 14, No. 8, back cover; The Linking Ring, Vol. 30, No. 2, back cover). Stuthard changed Hunter's glued fan of cards to a glued straight row of cards. The target card in the center was a loose half card that was stolen away in the second phase to create a vanish. Further details on the methods are given in Prolix, No. 9, 2012, p. 588.
