ABSTRACT:
A lightbox for display purposes, such as advertising, comprises a rigid back plate adapted to be secured to a support surface, a light source carried by the back plate, and a front fascia of clear plastics material which can be flexed and which is held in place in a curved attitude on the back plate by the engagement of fastening means between the fascia and back plate. The fascia comprises outer and inner panels which sandwich a photographic transparency therebetween. Flexing of the fascia for mounting on the back plate causes the two panels to come into area contact with the transparency. Release of the fascia from the back plate causes the panels to be loosened and enables the transparency to be removed.
