This deck isn't based on an existing deck, rather it uses elements from a 14th Century document. It's designed to be a mini-deck right now but I'm looking at making it a poker deck. The design for the backs of the cards is taken straight from the document.
The border on the faces of the cards is also taken straight from the manuscript. I'm changing the red interior border to match the red on the backs of the cards.
I've also, since I made these test images, darkened the 'parchment' background on the faces to more closely reflect the current state of the document. It also makes the colors pop a little better. The early decks didn't have queens, particularly the German and Swiss decks, but since Printer's Studio mini-decks have so many extra cards in the standard order I decided to put in four courts: King, Queen, Knight (mounted on a horse), and Knave/Page (man on foot). The players can customize their deck and decide which cards to leave out (German/Swiss decks didn't have aces either, just for example).
I also had a wide variety of possible suits to choose from. Since print-on-demand offers that sort of flexibility I'm making six: cups, roses, leaves, swords, hawks, and crowns. All can be documented in the 15th Century in Germany and Switzerland. I'll let the customer choose which four suits he wants his deck to contain.
