Abstract
A display device in which a banner towed behind a moving vehicle such as a boat, is stabilized by a self-regulating drogue parachute attached to the trailing end of the banner so as to maintain the banner in a vertical plane with its longitudinal axis substantially horizontal, for a wide range of air speeds. When not in use, the banner is wound onto a roller rotatably and removably mounted on a support carried by the vehicle.
