The most expensive book was a 19th century French work called Les Maîtres de L'Affiche. It sold for $43,450, edging out an original German copy of Das Kapital for the title. Other notable titles on this list include a signed first edition of John le Carré's Call for the Dead ($22,000).
Abe Books also sold a copy of an edition of Alice's Adventures in Wonderland which was illustrated by Salvador Dali and came signed by the artist ($20,000). Abe Books reports that only 2,500 copies were produced, containing 12 memorable illustrations from the surrealist (including the two shown above). And much further down the list, you'll find a signed second edition of The Hobbit, which sold for $11,000.
The list is 50 titles long, and ends with a first edition of Harper Lee's novel, which sold for $9,000. All of the titles listed are far outside my reach, although it is fun to read about.
