Cartão Retro Atomic Happy Labor Day

This lively Labor Day design bursts with mid-century Atomic Age energy and optimism. Set on a warm, lightly textured background, bold retro typography spells out “Happy Labor Day” in vibrant orange, golden yellow, and teal. Playful starbursts, atomic orbits, boomerang shapes, and confetti-like dots dance across the composition, evoking innovation, progress, and postwar American creativity. The upbeat color palette and graphic simplicity give this artwork a cheerful, modern-vintage feel.
