From the AbeBooks Blog:
It was a bumper year for rare bookselling. The combined total of AbeBooks’ top 10 most expensive sales during 2011 is $220,330. The November sale of Karl Marx’s Das Kapital for $51,739 was the year’s most significant transaction on AbeBooks and one that sparked many wry smiles.
The sale of a signed first edition of Harper Lee’s one hit wonder, To Kill a Mockingbird, for $25,000 illustrated that this novel remains one of the most desirable of modern firsts.
Our third largest sale was a complete set of all 10 issues of Aspen Magazine, a multimedia publication that ran from 1965 to 1971. Many leading figures in contemporary art, both British and North American, were contributors to Aspen including Andy Warhol, John Lennon, Timothy Leary and Susan Sontag.
