Die Preussischen Provinzen Preussen Und Posen Und Das Konicreich Polen (The Prussian provinces Prussia and floats and the Konicreich Poland)
An amazing large steel engraving from a great German cartographer. It's hard to imagine a better reference for this German province, whether it is for a geneaologist or traveller. Finely detailed it touches on all the small towns and roads that existed at the time, and yet are still very legible and attractive.
Condition is very good. Image size is 21 X 24 (inches).
