Joe Zentner wrote of the origins of the advertising campaign on the Desert USA website in "Twenty Mule Teams on the move in Death Valley". Bill Parkinson, formerly a night watchman for the company, had to learn quickly how to drive the team when he was given the role of "Borax Bill". He was the first, but not the last, driver known by that name. The 1904 St. Louis World's Fair was the maiden appearance for the team and was such a success that Parkinson went on tour.
