Bloomberg reports that 99 lots of ornithological books and prints from the collection of the late Chicago philanthropist Brooks McCormick will be sold at Sotheby's in New York on 5 October. The auction proceeds will go to the International Crane Foundation.
The full Sotheby's catalog isn't online yet, but Bloomberg notes that the sale will include 90 prints from Audubon's Birds of America, a first edition of Darwin's On the Origin of Species, and (drum roll please) a copy of Mark Catesby's Natural History of Carolina, Florida and the Bahama Islands (that's expected to be the high spot, estimated to fetch up to $600,000).
Another one I'd like to be a fly on the wall for.
