The image above is from The Encyclopaedia of Tarot, Volume II, p289. This and Volume one are two of the most important books you can buy to help with studying tarot history, and I highly recommend that if you don't already own copies you get them right away. They are an enormously important reference, and information and images from them are discussed frequently on this forum.
I have scanned the pages discussing the Sforza Castle cards because I think many of these cards are incredibly important for discussing the origin of the Tarot de Marseille. These are large scans so that you can read the information and see the images in moderate detail, I'll add one per post, and they can be clicked on to enlarge for easier reading. I look forward to what will hopefully be some interesting discussions.
