An advertising display system, for use with a portable toilet housing
having four walls and four corners connecting the four walls. A bracket
assembly is attached vertically along each corner. At least three panel
assemblies are each selectively mounted between two of the bracket
assemblies such that each panel assembly arcs outward to create a
substantially semi-cylindrical configuration by the panel assembly which
spans across one of the walls. Each panel assembly includes outer panels
and a changeable printed sheet extending therebetween. Each bracket
assembly includes a T-bracket which provides a space between the T-bracket
and the corner of the portable toilet housing to secure one of the panel
assemblies therebetween.
