Wal-Mart Stores Inc. is pulling a skull-and-crossbones T-shirt from its shelves after a blogger complained that the image was identical to a Nazi SS emblem from World War II. Rick Rottman, who runs an online journal called Bent Corner, posted a picture of the shirt late last week next to an image of a divisional insignia he said was used by the 3rd SS Division, a unit of Adolf Hitler's Waffen SS. The design is a distinctive image of a squat-looking human skull slightly angled to the side. The world's largest retailer said Monday it was not aware of the origins of the image until Rottman's post and is working quickly to get the T-shirt out of stores, spokesman David Tovar said. "We are deeply sorry that this happened, and we are in the process of pulling all of these T-shirts from our stores," Tovar said. "Respect for the individual is a core value of our company and we would never have placed this T-shirt on our shelves had we known the origin and significance of this emblem."
