Taking over for his father, S. Augustus Mitchell, Jr. continued one of the leading map publishing firms of the nineteenth century. His maps were standards in the industry and continue to be valued today for their depth of information and their clarity of presentation. This is a fine map of Illinois, highlighting its major city, Chicago, about a decade before its most infamous fire.
