This is a great website about the German mapmaker, Martin Waldseemüller. http://www.visualnews.com/2012/07/03/500-year-old-map-of-america-found-between-pages-of-a-book/?utm_source=VisualNews&utm_medium=email&utm_campaign=8032afa7d8-RSS_EMAIL
One of the first European maps to recognize the continental mass
known today as North and South America was discovered tucked between
the pages of an old geometry book in the Munich University Library. The
map, which is over 500 years old, was created by German cartographer
Martin Waldseemüller using data from Amerigo Vespucci’s voyages to “The
New World” from 1501-1502, hence the designation “America.” Until now,
the map had been lost sometime in the 19th century after being misfiled
in the university library. Including this one, there are only 5
versions of the map that are known to exist and one of them sold for $1
million at an auction in 2005.
Here is another website with great maps of Native America.
