“Maps: Finding Our Place in the World” will feature more than 130 famous or prized maps. Organizers, who will officially announce the show Friday, are billing it as the most ambitious cartography exhibit ever in North America. Pieces confirmed for display include a 3,500-year-old clay tablet detailing walls, gates and palaces in the town of Nippur in what is now Iraq; three drawings by Leonardo da Vinci rarely lent from the English royal collection; the map Charles Lindbergh carried with him on his history-making flight from New York to Paris; and drawings by author J.R.R. Tolkien of his fictional Middle-earth. [More]
