This map shows Pittsburg at the height of its power. Andrew Carnegie started production in nearby North Braddock in 1875, which jumpstarted the industry here. In 1901, U.S. Steel would be formed, and ten years later it contribute up to half of the nation's steel output.
Surrounding the map are advertisements by several Pittsburg companies, showing furnaces and other turn-of-the-century appliances.
