The Cary-Yale Visconti deck may be the oldest Tarot deck in existence. It is one of several hand-painted Italian decks that the Visconti family commissioned in the 15th Century. 67 cards remain in existence.
The Cary-Yale Visconti deck is unique in that it seems to have been created with 6 court cards per suit rather than 4 as in traditional Tarot decks. The knights and valets too come in a male and female version.
The deck was created between the 1420s and 1460s in Milan. It is sometimes ascribed to Bonifacio Bembo.
