First edition of Greenleaf's rare map of Maryland and Delaware, from the first edition of Greenleaf's Universal Atlas.
The first edition can be determined by the lack of a page number on the map and the lack of Sinepuxent Inlet, to the east of Snow Hill in Worchester County, among changes in the editions of the map. The map is colored by counties and shows towns and early roads. Greenleaf acquired the plates for the atlas from David Burr and made only minor changes outside of the map image. David Burr is among the most important American map makers of the 19th Century, having served a term as the chief cartographer of the United States. His maps are prized by collectors for the detail and high quality engraving style.
