A Map of Pennsylvania or La Pensilvanie by William Scull (Paris: Chez Le Rouge, 1778), outline color, presented in walnut frame, in three parts, overall dimensions 43 x 68 inches.

Originally included in Atlas Ameriquain Septentional published by Georges–Louis Le Rouge. The German-born George-Louis Le Rouge published these maps in Paris at a time when France renewed its active participation in American affairs. The maps meticulously show a rugged North American landscape between Canada and the Gulf of Mexico with details that would aid travelers – and armies - of that era. Accordingly, the Le Rouge maps became highly prized by strategists on both sides of the American Revolution. All plates in the Atlas are copperplate engravings of the period.
