A British auction house says a signed copy of Adolf Hitler's infamous manifesto "Mein Kampf" has fetched 21,000 pounds ($34,900).

Mullock's Auctioneers in Ludlow, in western England, says the semi-autobiographical book was sold to an anonymous telephone bidder Thursday.

The say the book is a prepublication copy given by Hitler to a fellow inmate in 1925 during his four-year prison term in Bavaria in southern Germany.

"Mein Kampf" outlines Hitler's anti-Semitic ideology. It was written in 1924, and was banned from publication in Germany after World War II.

The town of Ludlow is 124 miles northwest of London.
