The cards show lingering evidence of a suit system derived from early Arabic cards, which in turn became popular throughout Europe from the 15th century. They have been printed from wood blocks and coloured by a technique known as 'a la morisca' which involved using the fingers dipped into the pigment. This is different from other early packs of cards which were hand-painted or illuminated and therefore more expensive. As their popularity spread, new methods of production were discovered to produce packs of playing cards more cheaply. Cards in the Museo "Fournier" de Naipes de Alava.
