An outdoor sign resistant to wind damage includes a support column; a display having secured and released positions, a lower edge and a central vertical axis aligned with the axis of the column when the sign is in the secured position; a lower horizontal arm with opposed ends mounted on the upper end of the support column; an upper horizontal arm with opposed ends attached to the display, the upper arm being parallel to the display lower edge and the lower support arm when the display is in the secured position; a pivot mechanism joining the support arms adjacent one end; and a retainer mechanism between the opposite ends of the support arms, the mechanism releasibly securing the support arms to each other when the sign is in the secured position. The retainer mechanism is unlatched when the wind force is greater than a predetermined value.
