Two rare early editions of Mein Kampf, signed by Adolf Hitler could sell for more than US$20,000 (NZ$24k) at an online auction, officials say.
Nate Sanders, owner of Nate D. Sanders Auctions in Los Angeles, said he knew he'd catch a lot of flack for putting rare 1925 and 1926 editions of the racist screed up for bid.
''But it is a piece of history. It is a very rare item,'' he explained.
Hitler was arrested and jailed for the attempt to seize power.
He dictated Mein Kampf, two volumes of autobiography and anti-Semitic manifesto, to Rudolf Hess while behind bars to raise money for his criminal defence.
Both volumes' fly-leaves feature Hitler's signature.
Sanders said volumes of Mein Kampf from the 1930s are common, but a copy signed by the author was rare.
Sanders was also auctioning off a leather trench coat he said was worn by Albert Speer, a Nazi government minister who was sentenced to 20 years in prison for his role in the Nazi regime.
Selling Nazi memorabilia was prohibited in many European countries.
