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, Oct. 1916, p. 69. His ad for it appeared in The Magic Wand, Vol. 7 No. 1, Sep. 1916, p. 35. Joe Stuthard marketed an improved version called “Klip-Trick Monte” in 1950 (see ads in Genii, Vol. 14 No. 8, Apr. 1950, back cover; The Linking Ring, Vol. 30 No. 2, Apr. 1950, 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.
