Abstract: An inexpensive temporary vehicle door display device with a planar member with indicia such as a visual symbol, message or advertisement printed thereon, that includes an integrally formed edge member along a vertical edge that selectively attaches to the trailing edge of a vehicle door. The edge member has a door edge cavity that receives the trailing edge of the vehicle door when the device is installed. The planar member is made of thin flexible material designed to extend over and at least partially cover the outside surface of the door. The planar member may be color-coded to match the color of the door and includes at least one magnetic element attached to the inside surface of the planar member that holds the planar member over the exterior surface of the door. Printed on the planar member are indicia such as words, letters, numbers, images, advertisements or promotional materials.
