Payroll to Tombstone (1959), Grave Near Tombstone (1959) and The Hanging (1959) all supposedly happened the same day: 8/12/1881.
Here are many businesses and services seen in Tombstone throughout the series. Some might have been mentioned in various episodes without being seen: Tombstone Courthouse; Tombstone Cafe; Tombstone Hospital; Al Hambra Saloon; Lucky Clain Saloon; Hafford's Saloon; Oriental Saloon, selling Buffalo Lager - signs outside the door; Russ House - Good Food and Lodging; Barber Shop - Shave 15 cents, Haircut 25 cents; Livery Stable and Blacksmith; Dressmaker; Undertaker and Funeral Parlor; Birdcage Theater; Bank; Stage Depot; American Hotel; Arcade Hotel; Cosmopolitan Hotel; Grand Hotel and Saloon; Hotel Occidental; Lenoir's Furniture Store, next door to the sheriff's office; Express Office; Hardware Store; Silver Lode Bank. But the most prominent and famous is the newspaper, The Tombstone Epitaph.
The complete acknowledgement for the two persons listed in the Thanks section of every episode reads: "This series is produced with the / full cooperation of / Clayton A. Smith, / Editor of the TOMBSTONE EPITAPH, / and D'Estell Iszard, Historian"
The name of the editor of The Tombstone Epitaph, a very important character who also serves as narrator, is seldom used but was revealed to be Harris Claibourne. He is clearly inspired by the famed John Clum, reformer Indian agent and later, as editor, a supporter of Marshall Wyatt Earp. As such, Clum appears in many other films including the biographical Walk the Proud Land (1956).
