While commonly credited to Ed Marlo, because of its use in the second method in his 1945 booklet Future Reverse, this sleight is described, without attribution, in Greater Magic (1938), bottom of p. 339, in the context of a card prediction, in which the magician openly reverses a card in the deck, which later proves to be a freely named selection. (This Greater Magic reference was spotted by Denis Behr.) This effect, by the way, bears a resemblance to Marlo's “Future Reverse” effect, suggesting the item in Greater Magic was his inspiration. Marlo does not claim the sleight; nor does he cite a source for it.
