Five maps on one sheet. The most notable being a remarkably detailed printing of Gadsden or Arizona, 6 years before Arizona became a Territory. The earliest mention of Arizona on printed maps is around 1860. Aside from being one of, if not the earliest appearances of Arizona on a map is that the region is confined to the Gadsden purchase, and does not reach the Baylor Line. One if the very few maps to focus on the Gadsden Purchase. The second Norte Americano map tracks the Rio Bravo Del Norte from North of Multero to San Elceario, and showing Socorro, Isleta, Sinecu, El Paso, Fort Bliss, Frontera and other early places. Petermann's maps are often the only attainable examples of important maps of scientific exploration and travel.
