Birds of America; $11.4 million - This 3-foot tall book includes 1,000 life-size illustrations of 435 birds drawn by West Indian-born American artist John James Audubon in the 1830s. [Guinness]* What about Bill Gates’ $30 million purchase of Leonardo Da Vinci’s notebook “Codex?” According to Guinness, Codex does not technically qualify as a book as it’s filled with mostly sketches and notes. Sorry, Bill.
