摘要： A construction or emergency sign with a changeable message on its front surface. The sign has a diamond shape or a square shape and one or more flaps are secured along the central diagonal of the sign. The flaps are adapted to be releasably fastened to either of two opposite corners of the sign and have messages on both sides. When the flaps are secured in one corner, a first message is presented and when the flaps are secured in the other corner, a second message is presented. A pair of cross-braces hold the sign in a taut planar configuration. The sign is also adapted to be collapsed into a small, compact package for transport and storage. One embodiment of the sign has two or more flaps thus allowing three or more different messages to be presented. Another embodiment has an additional cross-brace allowing the sign to be used to present either diamond or square-shaped messages.
