Striking full color example of the first edition Greenleaf's map of Illinois, which appeared in his Universal Atlas, first issued in 1842.
The county system of Illinois is now substantially complete, although there are still a handful of counties in the northeast which are not yet created. The map depicts a number of early roads, including the National Road. A number of forts appear, including Ft. Dearborn. The Indian Boundary of 1829 is shown, as are early canals, mounds and the Winnebago Swamp.
