LOUISVILLE, Ky. (WDRB) -- Walmart is apologizing for a controversial sign placed above a display case of guns.

The picture of the sign reading "Own The School Year Like A Hero" was hanging above a case of shotguns at a Walmart. It surfaced on social media Wednesday night. 

The company's Twitter account responded to customers who posted a picture.

The company told CNN Wednesday it was working to identify which of its stores put up the exhibit.

Walmart also issued a statement, saying "what's seen in this photograph would never be acceptable in any of our stores."
