Abstract: An accessory is provided for mounting flags, typically favorite team pennants or insignia, on the rooftops of vehicles provided upwardly extending bars such as luggage racks by means of a clamping mechanism that orients a flagstaff vertically a predetermined distance above the rooftop, and thus provide high visibility without interfering with driver vision or damaging the exterior surface of the automobile. The flag vertically extends at a height that serves as a car finding signal in crowded stadium parking lots.
