The high-waisted, salmon-colored, lace-trimmed French silk underwear are on display in a glass case at the Mantiques shop in Elmore, Ohio, listed at a price of $7,500, according to The Daily Beast.

Embroidered with the initials “EB”, the undergarment is reported to have belonged to Hitler's wife Eva Braun, says the shop's owner.

“They’re first rate: the fabric, embroidery and monogramming, the sewing of the button,” manager Ernie Scarango told The Daily Beast. “Not everyone has Eva Braun’s underwear.”

Scarango said he was tipped off about the existence of the lingerie ten years ago and decided it would make a nice “conversation piece” for the store.

An auction was selling off hundreds of silverware, watercolour paintings by Hitler and other personal items that had supposedly been taken by Allied soldiers when they captured the Nazi party “Eagle's Nest” headquarters and Hitler's Berghof residence in the Bavarian Alps, Scarango was told.

The man who had acquired the knickers for the auction was Charles Snyder, a retired Air Force major who served in both Vietnam and Korea and owns his own online military memorabilia shop, Snyder's Treasures.

Snyder said that years ago, he had met a man named D.C. Watts, who told Snyder he had been in the 1945 liberation of the Nazi headquarters with the 506th Infantry. Watts told Snyder that he and a friend found a series of tunnels under Hitler's home leading to a hotel with boxes and boxes of Hitler and Braun's possessions and shipped them to the US.

Snyder eventually purchased all of the contents within those trunks, including many pieces of Braun's lingerie.

Whether the panties actually belonged to Braun is still up for debate. And Scarango told The Daily Beast that even if someone buys the story, it probably wouldn't be enough to actually buy the underwear.

“They’ll stick ’em in my casket when I die,” he said. “Are you kidding me? Who’s going to spend $7,500 for a pair of Nazi panties? If someone offered me the asking price of course I’d sell, and then I’d take them upstairs and make breakfast for them.”
