Prompt

Animate the 1958 Lincoln-Douglas Debates stamp while strictly preserving its original brown engraved artistic style. Do not add any new elements or change the scene. First, make Lincoln gently raise and lower his outstretched arm, as if delivering a dramatic point. Second, have the crowd in the foreground slightly nod and shift to show playful engagement. Finally, make the patriotic bunting on the platform sway softly, maintaining the historical and stoic atmosphere of the original artwork.
