Probably because I'm a dimwit, or due to lack of sleep, but I found this pretty funny.
For the record :
Correction: Because of a reporting error, a review of the Boston Public Library exhibit ``Journeys of the Imagination“ in last Wednesday's Living/Arts section mischaracterized a 1513 map by German cartographer Martin Waldseemuller. The map does not depict North America. It shows only part of South America and the Caribbean islands and does not indicate where they are relative to Asia.
Seems like a fairly large mistake: did anyone actually look at the map in question?
