Abstract

A plurality of elongated generally rectangular panel members are provided and include first and second sets of corresponding ends. A pivot fastener is secured through and pivotally joins one set of corresponding ends of the panel members together for relative angular displacement of the panel members. The panel members are swingable from a compact position with the panel members in full registry with each other and positions with at least one of the panel members angularly displaced relative to the remaining panel members. A spacing and friction washer is disposed between each pair of adjacent panel members and about the pivot fastener whereby the panel members may be frictionally retained in relatively angularly displaced positions. Each panel member is white in color and has word defining letters formed on its opposite sides with light reflective material of a color other than white. The word defining indicia on the opposite sides of each panel member are identical, the word forming indicia on the remote panel members is identical, and the word forming indicia on each panel member intermediate the remote panel members different.
