Tucked in the back part of the Cochise Hotel property is a wonderful Gambling Museum with gaming tables from the late 1800s and early 1900s. Owner Phillip Gessert is a master of Faro--the game played by Wyatt Earp--and will gladly teach you how to play!
Playing cards did not have the suit or card designation (called indexes) on them until around 1870.
The first cards with indexes were smaller versions of the card being played with part of the suit showing. In this hand, you have a six of hearts, six of spades, joker, and seven of diamonds.
