Attractive large format ethnographic map, colored by ethnicity, and showing the location of Serbs, Bulgares, Russians, Poles, Germans, Greeks, Romanians, Zinzares, Skipetars, Turks, Turkomans Yuruks, Tartars, Magyars, Jews, Arabs, Armenians and Tsiganes. Large inset showing the eastern part of Serbia and the Danube Delta and a smaller inset of Crete. Thematic ethnic maps are unusual in the 19th Century, especially for this region and in such large format. A nice collector's map. Augustus Petermann published a series of works in the mid to late 19th Century which compiled many maps of scientific travel and exploration. In most cases, the original maps are nearly impossible to attain, making Petermann's works highly collectable.
