A stunning vintage 1950s pin-up style illustration of a beautiful, elegant woman with perfectly styled upswept hair and refined facial features, holding a detailed anatomical human brain in her outstretched hands with a composed, knowing expression. Bold retro hand-lettered typography reads "HEY, YOU DROPPED THIS" in large blocky black letters to the left of the figure. Style: high-contrast black and white machine embroidery design with fine crosshatch line detail, thick outlines, textile stitch texture on linen-colored background. Flat vector graphic, no gradients, crisp bold linework, vintage advertisement aesthetic. --ar 1:1 --style raw
