The present disclosure provides for a customizable, portable billboard system. The portable billboard has a number of sidewalls enabling advertisement graphic placement. These sidewalls sit upon a support base that has structures, preferably wheels, which help to facilitate movement of the billboard. The advertisement graphical overlay is attached to the sidewalls via framing that surrounds the perimeter of each of the sidewalls. The entire system is self-contained and has a generator to power any lights or speakers or the like that may be required. The system has a hitch attachment so that it may be easily maneuvered or transported to a particular location by motor vehicle.
