A notice board has a body (1), and rotatably mounted on this body (1), a plurality of appropriately arranged segments (2). These segments (2), have faces of different colours, such that one face may be the same colour as the body (1), whilst the other face is of a colour that contrasts to that of the body (1). Rotation of a segment (2) thereby allows the selective presentation of either face, depending on whether that segment (2) is to present a visual contrast to, or to merge with the body (1) of the board. The body (1) and its segments (2) are preferably mounted on a supporting board (4) via an upper hinge (5) and a lower magnet (6) or other attachment. By appropriate positioning of the segments on the bodies and the visual presentation of these segments, (and possibly by having several such bodies and corresponding segments) the formation of selected groups of letters, numbers and other data is possible. <IMAGE> |
