This fascinating map was issued at the 150th anniversary of the signing of the Northwest Ordinance of 1787 and was published by The Northwest Territory Celebration Commission. The sheet features inset maps at bottom depicting how each state was formed, with insets at top showing the various Indian treaties that allowed settlement to extend west. The main map image is filled with historical notations and illustrations, and is decorated by a large compass rose. The verso contains the full text of the 1787 ordinance.
