Elmer Biddle published this sleight in Genii, April 1947, p. 241. Marlo maintained that Tony Kardyro had independently devised this steal and was using it some years before its publication by Biddle. However, a new contender, discovered by Max Maven, is Eddie Joseph. See his “Repeat Six Card Trick” in Strictly Magic, 1939, p. 8. The false count Joseph describes is identical to Biddle's in mechanics and intent, differing only in that the packet is held by its sides, as in a glide, rather than by the ends.
