2x2 grid, 16:9, do this for 4 underrated sports: Mid-century flat vector style, clean, flat vector illustration with bold shapes, high contrast, and minimal to no gradients; reminiscent of 1950s/60s commercial art and pulp sci-fi covers. The subject's gear and clothing are styled in Atomic Age or Googie retro-futurism (bubble helmets, finned rockets, ray guns, sleek metallic suits with geometric color-blocking, dials, antennas). The background features stylized, geometric cosmic or abstract elements (4-pointed sparkle stars, ringed planets, atomic orbital rings, abstract boomerang shapes) rather than photorealistic environments. Strict retro palette: a limited, vibrant mid-century color palette (teal, coral/orange, mustard yellow, cream, deep navy/black) applied as flat color fills. Stylized proportions and posing: slightly exaggerated, elegant, or dynamic proportions typical of mid-century fashion illustration (long limbs, sleek silhouettes, confident posing, stylized facial features). Crisp vector edges, intentional halftone dots optional, bold graphic impact.
