A rare edition of John James Audubon’s Birds of America, one of only 120 complete sets in existence, is expected to sell for $10 million during an auction at Christie’s in New York City later this month. The Guardian reported that the “new set was bought by the fourth Duke of Portland at some point after 1838 and is in ‘excellent’ condition.”
Richard Davies of AbeBooks said that even though the estimated value of the set is “sky high… [it] is in excellent condition [and] if the record does fall, then no one should be overly surprised because a rare book like this is recession-proof.”
