The purple on this map is really unique. I don’t think I’ve ever seen a historic map that used purple as it’s primary print color.

There is almost too much history in this map to note, but important to note is the location of Union Depot near the western Downtown riverfront. My interest in health system history makes me notice all the hospital as markers of place along with cemeteries.

HT to Paul Jones III, I found this map in the Rumsey Historical Map Collection
