Fascinating map of the continent showing the imaginary Sea of the West and a Northwest Passage stretching from Baffin's Bay to the Archipel St. Lazare through a complex system of lakes and rivers. There is not yet any sign of a recognizable Alaska. The British colonies are confined east of the Appalachian Mountains with French Louisiana stretching to the Pacific Northwest. Large decorative title cartouche that is uncolored.
Faint scattered foxing and tiny fold separation in bottom blank margin, well away from map.
