Scarce Railroad map of the Western United States, published to illustrate the lines of the Union Pacific and its major connecting lines.
The map illustrates the completed main lines from Omaha and Kansas City to Denver and Ogden, Utah, colored in red. The additional railroad lines are color coded, with lines reaching to Southern Oregon, western Utah, Ketchum, Idaho, Deer Lodge Montana, Crested Butte, Colorado, and all through the Gold and Silver Regions of Colorado.
The map was likely issued with some sort of annual report beginning in 1883, but is quite scarce on the market.
G. W. & C. B. Colton was a prominent family firm of mapmakers who were leaders in the American map trade in the nineteenth century. The business was founded by Joseph Hutchins Colton (1800-1893) who bought copyrights to existing maps and oversaw their production. By the 1850s, their output had expanded to include original maps, guidebooks, atlases, and railroad maps. Joseph was succeeded by his sons, George Woolworth (1827-1901) and Charles B. Colton (1831-1916). The firm was renamed G. W. & C. B. Colton as a result. George is thought responsible for their best-known work, the General Atlas, originally published under that title in 1857. In 1898, the brothers merged their business and the firm became Colton, Ohman, & Co., which operated until 1901, when August R. Ohman took on the business alone and dropped the Colton name.
