Prompt

Strictly preserve the original portrait style and the red, white, and blue color palette. Animate only the items already on the stamp: Dwight D. Eisenhower's portrait subtly nods, his expression turning into a slight, reassuring smile. The stripes of the American flag in the background wave in a continuous, flowing banner motion. The perforated border of the stamp do not change at all. Don't change them. Do not add new items.
