S. Augustus Mitchell, Jr., of Philadelphia, was one of the largest map publishers of the middle of the nineteenth century. The firm was founded by his father, who from around the middle of the nineteenth century issued atlases and maps of all parts of the world in all formats. The Mitchell atlases contained up-to-date maps which were as attractive as they were accurate. In this map, Milwaukee is detailed with its streets named, wards indicated in contrasting colors, and major buildings identified. With its bold hand-color, decorative borders, and interesting information, this is a fine example of the Mitchell firm’s output.
