Abstract: A mountable signage enclosure for encasing a graphic media comprising a frame being generally elliptic or having a substantially aerodynamic edge, an encasement for protectively displaying the graphic media through a clear covering through a front side of the mountable signage enclosure and allowing the exchange of the graphic media, a plurality of light emitting diodes perimetrically positioned to illuminate the encasement and the graphic media inserted therein, a power source for providing power to the light emitting diodes, a plurality of suction cups fixed to a back side of the mountable signage enclosure enabling the fixing of the mountable signage enclosure on a smooth surface; and optionally comprising a photovoltaic charging means providing an electric current for charging the power source. The mountable signage enclosure provides a stand-alone illuminated sign that can be easily installed in a variety of configurations, while allowing the quick exchange of the signage.
