Decorative borders and detailed state mapping give maps from Colton's General Atlas their handsome mid-nineteenth-century look, made for the growing American market for household and commercial atlases. The Colton business in New York issued the editions here in the 1860s, combining the United States with the rest of the world. Counties, railways and settlements are marked across the eastern states and the western territories whose boundaries were still changing, so Dakota and Wyoming sit beside Minnesota, Wisconsin, Louisiana and New England. City plans focus on Philadelphia, Baltimore, Chicago, St Louis, Louisville and New Orleans, and further sheets cover France, Switzerland, Scandinavia, the German states, Canada and colonial territories.
