(IL - Chicago) Guide Map of Chicago - Central/S. America While at the very bottomGuide Map of Chicago. Published by Rufus Blanchard, 146 Lake St. Chicago. 1869. A rare folding map by one of the best mapmakers of the city at the time. Prior to the disaster that would befall it and necessitate its reconstruction, this map shows the city developing. This was the year that many of the individual park districts were created and indeed in the western edge of the town are several large parks that hint at being connected by green belts.
