This is an attractive example of the 1828 Malte-Brun map of Prussia. The map covers part of modern day Poland and Lithuania and shows Holy Roman empire Circles, the Palatinate of Culm, Pomeralia, and Polish Prussia. Various, important rivers, islands, cities and other topographical details are noted. This map was published by Samuel Walker in 1828 as part of the American edition of Conrad Malte-Brun's System of Geography, Vol. I.
