An extremely rare copy of Nazi Party founder Adolf Hitler's manifesto Mein Kampf, inscribed and signed by the inspiration of today's neo-Nazis, is heading to the auction block along with his personal clothing, including monogrammed underpants, size 39.

The book, in which Hitler laid out his plans for the Nationalist Party and policies that ended in the killing of six million Jews and destruction of Germany, includes the inscription: "Only in battle will the noble man survive! Adolf Hitler on 18/August 1930."

Hitler's skivvies could sell for 5,000.

The highly respected auction house, Alexander Historical Auctions, of Chesapeake City, Md., which is selling the book in its September 13-14 online sale, said that on the day he signed it, Hitler was in Cologne giving a speech promoting the Nazi Party for the September 14 elections in which he won 107 of the 577 seats in the Reichstag.

The expected selling price is $15,000-$20,000.

Alexander also has several other Hitler possessions heading to auction, including the world globe kept at his Bavarian home, socks, a shirt, and his overly-large underpants monogrammed with "A.H." The description from Alexander said, "The shorts are surprisingly large: 19 inches long, with a waist of about 39 inches."

Hitler left them behind at Austria's Parkhotel Graz in 1938. They are expected to fetch $4,000-$5,000.

This D-Day flag could fetch $250,000 or more.

Alexander is known worldwide for its historical auctions, especially of items from the U.S. Civil War and World War II. In the upcoming sale of World War II items, for example, it is auctioning a desk clock partially melted in the U.S. atom bomb attack on Hiroshima, the U.S. flag flown over Pacific fleet headquarters during the Japanese attack on Pearl Harbor, and rarest of all, an American flag flown by a landing craft on D-Day which brought ashore a company of the valiant 115th Infantry Regiment.

The sale had been planned long before the recent clashes between neo-Nazis and leftist anarchists over Civil War monuments.

Alexander President Bill Panagopulos told Secrets that in past sales of Hitler memorabilia have been purchased by known collectors and museums, and he expects the same this time.

The D-Day flag could receive the highest bid. Panagopulos expects it to reach a price of at least $250,000, considering others others have sold for over $400,000.

Up for auction is a clock damaged at Hiroshima.

The sale also includes items from the Holocaust. One notable book is the primer for concentration camp gassings: "Sterilization, Decontamination and Disinfection Employment Instructions for Hospital and Laboratory of the Hygiene Institute of the Waffen-SS, Book 3." Also: German instructions on building a gas chamber.

Asked to comment, the auctioneer responded: "The shameful events we witnessed in Charlottesville last week underscore the need to preserve this material, display it, and educate those who so clearly don't comprehend how they evoke the horrors of World War II."
