Prompt

Preserve the retro large-letter vintage postcard aesthetic and vibrant 1940s color palette. Animate only the existing items on the stamp: the giant 3D-style 'KANSAS' letters bounce playfully into place one by one. Inside the letters, the tiny combine harvester drives forward, its reel spinning rapidly. The puffy white clouds in the background drift quickly to the right. Do not introduce new objects or change the scene.
