A human skull in side profile sits alone on a white background, with fine cracks across the cranium and shaded bone around the jaw and teeth. Two solid black square frames hide the finder squares, one set against the forehead and one hanging below the cheek like an earring. The dark modules form a mottled pattern across the temple, eye socket and cheekbone, so the bone texture itself carries the data. Pure black against pale gray and white keeps the pattern sharply separated from the shading.
