Used book-selling website AbeBooks' biggest sale in 2011 was of Karl Marx's "Das Kapital," the three-volume first edition published by Otto Meissner in 1867. Ironically, someone paid $51,739 for the seminal critique of capitalism.
The second-highest sale on the site was of a first edition of Harper Lee's "To Kill a Mockingbird," published in 1960. This copy of the American classic sold in May for $25,000; the high price tag probably came from it being signed by Lee herself. Now 85, Lee largely withdrew from public life after the publication of her first novel a half-century ago. Signings are rare; she never published another book.
In the spring of 2011, Lee emerged from her quietude to issue a statement through her sister's law firm repudiating an upcoming book, "The Mockingbird Next Door: Life With Harper Lee." The book by Marja Mills, a former Chicago Tribune reporter, was said to be written "with direct access to Harper and Alice Lee [her sister] and their friends and family." In the written statement, Lee said she had not cooperated with the author: "Contrary to recent news reports, I have not willingly participated in any book written or to be written by Marja Mills. Neither have I authorized such a book. Any claims otherwise are false."
Meanwhile, Lee memorabilia has begun surfacing elsewhere. A number of letters and cards written by the author to a fan were sold in 2011 by Nate D. Sanders auctions. The chatty letters included thanks for gifts, the occasional note about her work and one letter which asked, "Please don't put this on the internet."
The Internet was one thing that Karl Marx wasn't worried about.
