There are only 119 known copies of John James Audubon’s “Birds of America” and one of them is coming up for auction (Sotheby’s PDF brochure). You have until December to pull together the estimated $6.2-$9.2 million to get a chance at owning this significant volume which contains hand-colored, life sized illustrations of about 500 birds. A copy auctioned in 2000 still holds the record for highest price paid for a book at $8,802,500. The University of Pittsburgh has digitized their copy  and placed it online with a handy search feature.  Audubon worked with engraver Robert Havell, Jr to create the illustrations; Wikipedia states that he engraved all but the first 10 plates.
