Ace :)

An ace is a playing card, die or domino with a single pip. In the standard French deck, an ace has a single suit symbol located in the middle of the card, sometimes large and decorated, especially in the case of the ace of spades. This embellishment on the ace of spades started when King James VI of Scotland and I of England required an insignia of the printing house to be printed on the ace of spades. The mark served to identify the printing house and to confirm payment of a stamp tax. Although this legal requirement ended in 1960, many card manufacturers have continued the custom. In other countries the stamp and embellishments are usually found on ace cards; clubs in France, diamonds in Russia, and hearts in Genoa because they have the most blank space.
