Signed copies of Mein Kampf for sale. That’s right, two rare copies of Mein Kampf signed by Adolf Hitler are being auctioned online this week—and bidding for these early editions of the Nazi leader’s manifesto begins at $20,000. Hitler reportedly gave the volumes to Josef Bauer, an early leader of the Nazi party, as a holiday gift.

The online auction is being run by Nate D. Sanders Auctions, whose owner, Nate Sanders, defended his decision to sell the controversial items, saying, “But it is a piece of history. It is a very rare item.”

The auctioning of Nazi memorabilia does not stop there. Sanders is also auctioning off a leather trench coat worn by Albert Speer, a Nazi government minister who was sentenced to 20 years in prison for his role in the Nazi regime.
