Between November 2 and January 27, there will be a maps exhibit at the Field Museum in Chicago. Not many details yet, except that it’s called “Maps! The History of Cartography” and it’s co-sponsored by the Newberry Library — and that three maps from the Tolkien collection at Milwaukee’s Marquette University, which houses the author’s papers, will be a part of it.
Update, Sept. 4: This is November 2, 2007 to January 27, 2008. No wonder the details are sparse. The Tribune report is apparently in error. Thanks to Tony for pointing out what I missed.
