"A Physical Planisphere wherein are represented all the known Lands and Seas in the Great Chains of Mountains w'ch traverse the Globe, from the North Pole adapted to Mons. Buache's Memoire",
The map depicts Buache's famous north polar projection showing his theory that the mountain ranges of the world are connected across the ocean basins. Nice early impression. Evenly toned and trimmed into engraver's signature at bottom with small splits on folds. Ref: Jolly GENT-104.
