The 496 year-old Waldseemueller map, the first map to use the word “America” to describe the new world, is on display at the Library of Congress.

The library recently completed the $10 million purchase of the 12-panel map covering 36 square feet, the most expensive single item it has ever acquired. It was owned by Prince Johannes Waldburg-Wolfegg, at whose castle in southwestern Germany the document was discovered a century ago. It is the only one known to survive of the 1,000 copies of the map said to have been printed.
