Hi, Happiness --
According to Stuart Kaplan, Johann Georg Rauch designed the first Swiss 1JJ deck circa 1831 to 1838. Kaplan says, "Rauch is known to have worked in Diessenhofe between 1831 and 1838 and was one of the predecessors of the firm of cardmakers now known as AGMuller & Cie. The engravings on the cards are hand-colored, and although the figures are stiff and awkward, the drawings are less crude than those of many other tarot decks of the time. Many of the cards have images like the Tarot of Marseilles, but do not follow the pattern closely. Cards II and V are changed from the Popess and the Pope to Junon and Jupiter. The deck is similar to the Swiss 1JJ deck currently published by AGMuller & Cie."
Kaplan saw a Swiss 1JJ deck at a toy fair, and bought a bunch of them to sell to bookstores in the U.S. It was the success of this venture that led him to start U.S. Games Systems, Inc., and a few years later he bought the rights to the Rider-Waite deck.
The 1JJ title comes from the renamed cards, Junon and Jupiter.
