Scarce map of the whole United States following the Civil War, published by G.W. & C.B. Colton.
The map includes eight vignette scenes around or within the decorative floral border, and a large inset map at lower left, "United States of America Showing Isothermal Lines and Zones of Equal Average Temperature."
The map shows the nearly-evolved boundaries of western states and territories, with the major unfinished delineation being Dakota and Wyoming attached as one; the proposed and nearly completed rail lines across the plains are shown, as are explorers' routes, recent forts, and much comment about the country.
The Gold Region of Colorado is prominently shown.
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.
