This variety of divided deck, used for card locations, appears to predate the red-black divided deck by centuries. It is described in “Sloan 424”, estimated to have been written in the 1600s; see Gibecière, Vol. 5, No. 2, Summer 2010, p. 142. It also appears in Ein Spiel Karten by R. P., Prague, 1853, Part II, item 4, p. 48 of the Pieper translation, titled “The Quickly Found Cards”. And Reinhard Müller reports finding the description of a divided pack (nature of division not stated) in Verschiedenes zum Unterricht und zur Unterhaltung für Liebhaber der Gaucheltasche, des Magnetismus, und anderer Seltenheiten by Hofrath von Echershausen, München, 1791.
