mediumaevum: dated c.1430 Originally in the collections of the dukes of Bavaria, these are considered amongst the earliest surviving sets of playing cards. The cards are made from pasteboard consisting of up to six sheets of paper glued together, over which, on the front side, a layer of gesso was applied. Outlines of the designs were scratched into the surface, while some details were drawn in with pen and ink. The entire surface was gilded and the designs were then painted over the gold.
