Rare map of South America by George Bauerkeller in Darmstadt.
The map incorporates the work of a number of important explorers, including Bach & Bulow, Castelnau, Codazzi, Darwin, Duperey, Gardner, Hall, Hamilton, Humboldt, King, Miller, Molien, D'Orbigny, Pentland, Parish, Poppig, Reden, Renegger, Restrepo, Schomburgk, Smith & Low, Spix & Martius, Tschudi, Villarino, and Wappaeus.
Bauerkeller's maps employ a unique printing process which combines letterpress, color lithography, and metal plate printing. His work is quite unique and enjoys an unusual visual appeal. Relatively little is known about Bauerkeller. He is best known for inventing a type of relief printing for city maps called "geomontographie." The city blocks with buildings are raised in white, while streets, squares, parks & rivers are printed in colors.
