A demountable road sign intended primarily for transient utilization includes a collapsible ground engaging support, a pivoted pantograph-type frame and a rolled, self-storing sign. The support preferably includes an elongate rod or similar structure which may be maintained in a vertical orientation by a plurality of attached legs. The legs are movable from a stored position generally adjacent the elongate rod to a deployed position in which they extend uniformly and obliquely away from the rod and engage the ground. Suitable structures for receiving the elongate rod support and securing the frame thereto form a portion of the frame. The frame includes a pair of preferably equal length arms pivotally interconnected at their mid points and a sign receiving device disposed on one end of each arm. The ends of the arms are interconnected by a pair of shorter pivoted arms. The sign is a flexible panel having indicia appearing on one or both sides which is furled on a spring-biased roller disposed within a protective elongate housing. The housing is received within the sign receiving devices and the sign deployed across the open frame where it is retained by engagement with suitable clips.
