Asda shoppers were baffled after spotting a "mysterious" image on their milk cartons.
The supermarket's own brand long-life whole milk features a cow in a field as the main picture. But behind the cow and below the product name is a random rectangle - and it has left buyers mystified over why it is there.
One shopper took to Reddit to question it. They wrote: " Asda milk carton has a mysterious white rectangle on the hills. Why?"
