A graphic sign fixture is described for use with a vehicle. The graphic sign fixture comprises at least two legs, a sign frame system, and a graphic sign. Each leg includes an upper post section, a lower post section, and a base section. The sign frame system comprises either a silicone edge graphic frame or a first sign frame cross-section member; a second sign frame cross-section member; and a locking system. The weight of the vehicle holds the legs in an upright position when the vehicle's wheels contact the base sections. The method comprises providing a graphic sign fixture, assembling the graphic sign fixture, and placing the wheels of a vehicle in contact with the base sections of the graphic sign fixture, such that the weight of the vehicle holds the legs of the graphic sign fixture in an upright position.
