A sign comprising a base member (10) supporting resilient arms (11 and 12), and a flexible sign panel (15) attached to the base (10) and arms (11 and 12). During use, wind pressure on the sign causes its upper portion to belly and moves arms (11 and 12) inwardly thus lowering the centroid of the wind force applied to the sign and enhancing its stability. |
