Abstract: A flag display device adapted to be mounted on the exterior of a vehicle or other object on which a flag may be displayed. The flag display device has a base, a plurality of spaced apart suction cups carried the base which are adapted to grip an exterior surface of the vehicle; a flagstaff; clips for attaching the flag to the flagstaff; and a mount for mounting the flag staff on the base and adjusting the angle of the flagstaff relative to the base so that the flag may be positioned at a desired angular attitude. The mount has a first toothed member integrally formed with the base which extends upwardly therefrom and having its teeth arranged on one side and projecting outwardly in a direction generally parallel to the base. A second toothed member is integrally formed with the lower end of the flagstaff so that its teeth intermesh with the teeth of the first toothed member.
