Rare map of the Northern Hemisphere.
The map shows the Northern Hemisphere as it appeared after Cook's voyages.
Johann, or Johannes, Walch (1757-1816) was a painter and engraver. He was well-known for painting miniature portraits, having trained in Geneva, Venice, and Rome. Walch published several atlases and sheet maps. As with his atlases, many of Walch’s maps were reprinted after his death.
