A sign comprises a plurality of elongate parallel-edged plank-like panels 10, 11 assembled edge-to-edge one above the other in a substantially common vertical plane. The abutting edges of adjacent panels are provided with respective cooperating formations 13, 18 which engage to lock the edges together to prevent their separation while the panels are confined to the vertical plane, for example by securement to posts. The sign may be attached to posts by means of channel members 12. The formations 13, 18 may be provided on one side of the panels only so that the sign presents a flat front surface with all of the formations on the rear surface. The cooperating formations are such that assembled panels are assembled together and may be separated, by rotating one panel about the edge of another (Figure 3a). <IMAGE> |
