A first edition copy of author Philip Roth's Pulitzer Prize-winning novel American Pastoral has sold for $80,000 (£50,000) at auction.

The book was the top draw at the First Edition, Second Thoughts event at Christie's New York on Tuesday (02Dec14), during which 75 titles, signed and annotated by the writers, were sold off to benefit the city's PEN American Center literary society.

Novelist Don DeLillo's Underworld was snapped up for $57,000 (£35,625), while Roth's Portnoy's Complaint went under the hammer for $52,000 (£32,500).

Other items included titles by rocker/author Patti Smith and Robert Caro and Woody Allen's book version of his Broadway production Play It Again, Sam, which only attracted a closing bid of $4,000 (£2,500).

The whole auction raised over $900,000 (£562,500).

American Pastoral, a family drama set during the Vietnam War, was published in 1997. It has since been optioned for a movie to be directed by Phillip Noyce and starring Ewan MCGregor, Jennifer Connelly and Dakota Fanning.
