Walmart, Sears and Amazon pulled a poster of Nazi Germany's infamous Dachau concentration camp sign that read: "Arbeit macht frei," which translates to "Work makes you free."

According to ABC News, Walmart said in a statement, "We were horrified to see that this item was on our site. We sincerely apologize, and worked quickly to remove it. The item was sold through a third-party seller on our marketplace. We have shared our disappointment with them and have learned they are removing the publisher of this item entirely from inventory.”

The link where the sign was on Walmart's website is now broken.

"The item, which was listed by an independent third-party on Sears Marketplace, violates our guidelines and was immediately removed," Sears said in a statement.

However, Amazon has not yet released a statement.

According, writer Jennifer Mendelsohn tweeted a screenshot of the Sears listing of “similar items," which included double wall ovens.

In response, Sears told, “Regarding the placement of the Sears products at the bottom of the Web page, those are special sale items that currently appear on millions of product pages. While clearly unintentional, we sincerely apologize for the proximity of the positioning.”

While Amazon also removed the poster, the e-commerce site is still selling Holocaust denial books such as: “Did Six Million Really Die? The Truth At Last.”
