Featured in this lot is this Wyatt Earp handwritten calculations on Happy Days Min board and was displayed in the Tombstone Western Heritage Museum; Provenance: From the Tombstone Western Heritage Museum in Tombstone, Arizona. Wyatt Earp, best known for his role in the Gunfight at the O.K. Corral, was also involved in various mining ventures after leaving Tombstone, Arizona. One of his more notable later pursuits was the Happy Days Mine in the early 1900s, located near Vidal, California, along the Colorado River. Earp and his common-law wife, Josephine Marcus, lived in the area seasonally while he worked the mine, which produced gold and was modestly profitable. Although the Happy Days Mine never brought Earp the fortune he sought, it reflected his lifelong pattern of chasing opportunities in the American West—from law enforcement to gambling to prospecting, long after his days as a Tombstone lawman had passed. The board features a length of sturdy hard wood with hand written in pencil mine calculations that were translated by the Museum Curator as follows: 42 - Thur 37 - Wed 39 - Tuesday 24 - 4.0 - Mon. ?.
