Nice example of Mathew Carey's map of Pennsylvania, one of the best large format maps of the state to appear in a commercial atlas.
The map is attractively hand-colored by counties, showing towns, roads, mountains, rivers, lakes, and a host of other early important details.
This first appeared in Carey's General Atlas, which was published in 1814. This was the first American Atlas to be offered for sale with hand coloring on the maps.
Original hand-color in outline. Faint toning at the centerfold.
