ABSTRACT An advertising support comprises a housing (1) with lateral edges which are designed to link up with further supports and are each provided with two supply rolls (3) that turn in the same direction, and can be reversed. The publicity material (7) is secured between two perforated adhesive viewing films (4) at a certain distance according to the width of the posters (7) to form insertion pockets of equal dimensions for receiving the posters (7). The web thus formed is then firmly bonded to a support film (8) facing the surface of the supply rolls (3). Metallic coding marks (9) are provided directly on the poster (7) in such a manner that the distance between said coding marks (9) can easily be modified without damaging the adhesive viewing film (4). The signals of the coding (g) are fed to the ROM memory of a CPU. They cause both driving engines (11) to switch over to slow motion through the CPU shortly before the image position is reached. The viewing windows (12) are covered with one or several viewing films (13) which become transparent when a given voltage is applied and non-transparent when the voltage is switched off. The distance between the poster (7) and the viewing film (4) is such that the contrast transmission from the surface of the poster is reduced.
