It took awhile to locate on-line, but I just found this Letter to the Editor written by Harold Eyster and published in the Wall Street Journal on December 4th. The article to which Harold refers, Stalking a Masterpiece from the November 26th WSJ, is also linked in his letter.
December 7, 2010 follow-up: Sold today, first edition Birds of America by John James Audubon. You can read about it in The Birdbooker Report.
The University of Michigan Graduate Library also has a copy of Birds of America currently on display.
