Important Revolutionary War era map of Pennsylvania, compiled by Sayer & Bennett, primarily from William Scull's landmark map.
This large and impressive map of the colony of Pennsylvania was published just a few months after the battle of Lexington and Concord. The map relies heavily on the landmark map executed by William Scull in 1770. Scull's original map is exceedingly rare, and noteworthy for showing the extensive Pennsylvania frontier, including western roads, paths, forts and other buildings, and the newly executed Mason-Dixon line.
Sayer & Bennett provide a revised and improved version of Scull's map, with clearer topographical delineations and including latitude and longitude markers. These improvements were likely added to aid British troops fighting in North America.
