Abstract: A poster display, subject to out-of-door wind forces that will develop substantial overturning forces against the poster display, is provided with a self-righting feature by using a hollow support base, with a convex support side that permits of rocking motion and that is ballasted by a flowable ballast material such as water, and upon which base, an upright, wind-catching, panel is mounted to project away from the convex support side. The base and panel are molded of inexpensive plastics. The base and panel may be formed as separate parts, or as an integral assemblage. In one preferred construction the base and panel are separate parts, have interfitting tongue and socket provided on adjacent portions of the two parts. The panel is preferably provided with a transverse edge flange that bound the region adapted to receive a removable display sheet thereonto.
