Abstract: Some embodiments of the present disclosure include a banner display system for displaying a banner lengthwise over an automobile. In some embodiments, the banner display system may include a first clamp assembly and a second clamp assembly, each clamp assembly including a C-clamp and a pole slot, and each clamp assembly configured to removably attach to an automobile, a first pole extending upwardly from the pole slot in the first clamp assembly; and a second pole extending upwardly from the pole slot in the second clamp assembly. A banner may be secured to each of the first pole and the second pole, resulting in the banner being displayed lengthwise over the automobile. In embodiments, the poles may be made of a bendable material, such that the banner is able to gently move without damaging the display assembly or the vehicle.
