Poster design for a US car meet, 1950s vintage retro style, background featuring a classic American diner or gas station with nostalgic charm, foreground showing a shiny 1950s Cadillac. A man in a leather jacket and rolled-up jeans leans casually on the car, a woman in a petticoat dress with red lipstick stands next to him, both in typical 1950s poses. Generous open composition with plenty of space at the top, bottom, and sides for text placement, harmonious sunny lighting, bright and vivid colors, stylized illustration like a classic retro poster, central focus on the car and people, flexible cropping for portrait or landscape orientation, dynamic and inviting atmosphere, detailed textures, clean lines, poster-ready.
