1. A wind-driven poster display system comprising
a) a stator assembly comprising:
i) a foundation base; and
ii) a foundation rod extending from said foundation base;
b) a rotor assembly configured to rotate about the stator assembly and comprising of:
i) a poster mounting frame comprising:
a top extension having a top extension slot;
a bottom extension;
a left extension and a right extension, each extending from the bottom extension to the top extension on opposing sides of the poster mounting frame to form a window in said poster mounting frame to receive a poster therein, and wherein each of the left extension and right extension comprise a U-channel to retain a side of said poster;
ii) a wind-capture mechanism comprising:
a wing blade extending from each of the left extension and right extension, in opposing directions from the poster mounting frame; and
c) a stator-rotor coupling assembly configured between the stator assembly and rotor assembly comprising a bearing portion that enables the rotor to rotate about the stator assembly;
wherein the wing blades are configured to create a rotational force on the poster mounting frame when wind blows across the wind-driven poster display to cause the poster mounting frame to rotate about the stator assembly; and
wherein each of the wing blades comprises a first extension portion extending from the poster mounting frame and a second extension portion extending from the first extension portion at a second offset angle that is less than 180 degrees.
