I wish my budget extended to collecting actual antique decks, but it doesn't. I dabble in recreating and selling playing card decks from the late Middle Ages and Renaissance. These are mostly for my own amusement, but print-on-demand technology means I can offer the designs to other people without having to invest money in a print-run. I'm a little fascinated with the early history of playing cards.
I've done a set of German/Swiss suits. Up until a week ago I let people choose their own combination of suits and backs. That got too time-consuming so I had to stop. I added Latin (Spanish) suits because someone asked me to. I kind of regret doing it now. You can see the suits, less the clubs and cubs, in this image.
My favorite deck is the simplified Topkapi/De Unger deck. I've been working on doing a deck in this style for a while and this black and white layout set was strangely compelling. I've had to alter size and proportions to fit modern cards but these are very true to the originals and I like them a lot. The full color/detail version is coming along very slowly.
My second favorite deck is the Barcelona/Moorish/Wintle deck. I know these were almost certainly a European deck done with European courts, but I imagined the deck as an actual Moorish deck and completed it with Islamic style courts. This is my third iteration of the deck and despite all the mistakes I've made I still love this deck. I'm currently re-doing this as a Spanish style deck.
I've done several others and I've got about eight more in various stages of completion. My research into French cards brought these volumes to my attention and I thought I'd share with anyone who wasn't aware of them. I haven't had any issues opening these documents up. Are you perhaps located outside the United States? You can try searching by going to the Haithi Digital Trust homepage and searching on the author. Searching on Cartes a Jouer will return an even large list of sources, of course.
