ABSTRACT:
Several embodiments of low cost advertising displays that achieve a visual or animated effect through the use of air currents or the like. In each embodiment a pair of juxtaposed pieces are supported in spaced relationship and for relative movement. At least one of the pieces is transparent in part and the pieces are formed with markings thereon which give a visual or animation effect upon relative movement between the pieces or upon movement of the viewer relative to the display. In some embodiments, the pieces are integrally connected by relatively thin strips of the same material which permit the relative movement and provide the relative support.
