While invariably credited to Ed Marlo due to its inclusion in Faro Notes, 1958, p. 29, this principle appears in Jacob Daley's Notebooks, nd. (c. 1974), np. (Item 37), as “Vernon's Mix Up Weave Shuffle.” The 76-76-67-67 formula is given. The deck is given two faros and half the deck is reversed to bring all the cards either face down or face up. Daley kept his notebooks through the 1930s and 1940s, so one can speculate that Dai Vernon came up with this idea earlier than Marlo.
