2093913 9303471 PCTABS00019 A rotatable display element has a reflective indicating vane comprising a thin sheet which is mounted so as to be in a substantially planar state. Such a thin and light sheet typically has little or no structural rigidity and preferably, according to this invention, the means for mounting the sheet are arranged to provide a tensioning force in the sheet. This causes the sheet to be held in a substantially planar state. The sheet according to this invention is also preferably arranged to be easily removed and replaced when it becomes faded or soiled.
