The sign has a base (4) with a first side edge, which is rotatably connected with a first cladding plate (1) along a track that outgoes from a corner point (10). A second side edge of the bottom is rotatably connected with a second cladding plate (2) along the track. A counter edge (14) opposing to the corner point is free such that the base is folded between the cladding plates. A foldable additional cladding plate is operatively joined to the base such that the folding of the base causes folding of the additional cladding plate between the cladding plates. The cladding plates consists of from Plexiglas (RTM: Polymethyl methacrylate) or polycarbonate, and are designed as composite boards with a plastic layer such as polypropylene layer, which lies between two aluminum layers. |
