ABSTRACT:
A device comprising a box having a transparent wall illuminated from the inside. The advertisements are joined to form a single flexible strip support which is wound and unwound between two parallel rollers. One of the rollers is fitted removably to the frame of the device, for enabling the support to be changed, and is rotated intermittently by an electric geared motor. The other roller is rotated by a torsion spring which provides for constantly tensioning the support.
