A banner is a flag or another piece of cloth bearing a symbol, logo, slogan or another message. A flag whose design is the same as the shield in a coat of arms is a banner of arms. A bar-shaped piece of advertising material sporting a name, slogan, or other marketing message is also a banner. Banners may hang from horizontal or vertical flagpoles, be stretched between two poles, be attached to windows or buildings, or be towed behind aircraft.
