Well, per Rusty (whose encyclopedic knowledge I trust!) it's photoreproduction of the Camoin Bicentennial reprint of the Conver, but it uses a later color scheme, which I read very recently on the camoin.com website isn't accurate (1880 colors) with the original. I do find it aesthetically pleasing, but for a new-looking deck with closer-to-original colors, the 1998 Camoin/Jodo deck is more what the 1760 Conver had goin' on. So the line drawings are original Conver, but the colors are what the same company was using in 1880.
BTW - the book does appear to have some interesting info, although as far as increasing one's knowledge of how to read Marseille, it's not a good match for the deck. (Like in revolutionary France, "Valets" became "Egalite" - that's cool trivia, but not much help when interpreting a spread LOL!)
