The Pony Express was a fast mail service crossing the North American continent from St. Joseph, Missouri, to Sacramento, California, from April 1860 to October 1861. Since 1866 until 1990, the Pony Express logo was used in security business. Presently, "Pony Express" is a trademark for postal services in Russia (by Freight Link) and the US (by the United States Postal Service). Glenn Danford Bradley (1884-1930) was the American author of The Story of the Pony Express (1913), Winning the Southwest (1910) and The Story of the Santa Fe (1920) "This little volume has but one purpose - to give an authentic, useful, and readable account of the Pony Express. This wonderful enterprise played an important part in history, and demonstrated what American spirit can accomplish. It showed that the "heroes of sixty-one" were not all south of Mason and Dixon's line fighting each other. And, strange to say, little of a formal nature has been written concerning it. "
