ABSTRACT:
A selective message display system comprising a pair of plates facing one another and in a spaced apart relationship to form between them a space. The outer faces of the plates bear insignia, such as parking restriction notifications. A movable display panel is mounted between the plates. The faces of the display panel bear additional insignia that override or complement the parking restrictions on the plates. The display panel can be placed in an exposed position in which it projects laterally from the plates so it is visible to motorists. The display panel can also be retracted between the plates to hide it from view.
