Birds of America The World's Most Expensive Book

Birds of America was first published as a series of sections between 1827 and 1838. Only 119 copies were published of which fewer than a dozen are in private hands. Each of the printed book were colored by hand, and it was an extremely laborious process. Even by today's standards, the vividness of its illustrations of birds is extraordinary but when it was being released in the 1830s it was mindboggling.

Audubon employed a rather shocking technique to produce the book. He hunted the birds down and shot them before propping them up on wires to paint. Each drawing would take about 60 hours to complete. Ironically, many of his beautifully rendered subjects are now extinct, such as the Carolina Parakeet, Passenger Pigeon, Labrador Duck, Great Auk, Esquimaux Curlew, and Pinnated Grouse.
