Nazi memorabilia including Hitler's top hat and a cocktail dress worn by his companion Eva Braun is going under the hammer at a German auction house, drawing calls from the Jewish community to stop a sale it deems immoral.

The collection features items such as the cigar case of Nazi air force commander Hermann Goering, Nazi military accolades, banners and knives, and a silver cased copy of Hitler's political treatise "Mein Kampf.

The collection is expected to fetch hundreds of thousands of euros. The asking price for Hitler's hat alone is €50,000 ($55,325) and the price tag for the deluxe copy of "Mein Kampf" that belonged to Goering is €130,000.
