This French map is one of the most interesting maps of the Great Lakes.  It maps the region from James Bay to just below Ft. Duquesne (today's Pittsburgh) and from Lake Ontario well into the Great Plains.  Many Indian tribes (Iroquois, Illinois, Sioux, etc) and forts including Detroit, St. Louis, Toronto and Chicagou, fur trade routes and missions are shown. Lake Superior contains Isle Royale, as well as the phantom islands of St. Anne, Maurepas and Ponchartrain, which were reported by the Jesuit explorer Charlevoix.  The source of the Mississippi is shown but is noted as inconnu or unknown.  Engraved by Andre.  Hand colored and matted.
