Retro Big Burger Fast Food Poster

The image presents a retro American fast-food poster style, with the main subject being a giant triple-decker beef burger occupying the central position. The top layer of the burger is a golden sesame-seed bun, with three thick layers of brown beef patties in the middle. Between each layer of patties, melted orange-yellow cheese flows over the edges of the patties. Below the patties are bright red tomato slices, deep purple onion rings, and crisp green lettuce leaves, with a white bun at the very bottom. The background features a distressed gray textured surface, surrounded by text elements in multiple styles: at the top is a large red bold title reading "BIG BURGER," with yellow promotional text below such as "BEEF, CHICKEN." Small black handwritten-style text is distributed on the left and right sides, with an overall staggered layout, and some text features a graffiti effect. There is a red circular logo in the upper right corner of the poster. The color palette is strongly contrasting, dominated by red and yellow, highlighting the appetizing texture of the food and creating a retro yet vibrant fast-food advertising atmosphere.
