CHICAGO IN EARLY DAYS framed print

"1779-1857.", "Reproduced in 1974 by HISTORIC URBAN PLANS, Ithaca New York from a lithograph in its collection". There might be something else written under that hidden by the frame, there's nothing showing on the backside of this poster size print that I haven't removed from its frame. That's all I know about it except that I think its cool, and I've also always loved Chicago anyways...?? ;-) :-) :-)
