A display device for an inside surface of a cooler door has a frame with a front panel and opposed first and second side panels. A top tube is mounted between the first and second side panels behind the front panel of the frame. A display scroll entrained about the top tube forms a top loop and a bottom loop. A bottom tube with opposed end flanges rides in the bottom loop of the display scroll with the end flanges retaining the bottom tube in the bottom loop. As the scroll is rotated about the tubes via a motor, a display graphic on the scroll moves to attract the attention of potential consumers.
