Surreal pop art vector illustration of a massive vintage astronaut helmet in close-up, its curved glass visor containing an entire miniature ocean, curling waves and one tiny sailing ship beneath a pale moon. Intricate woodcut engraving on the helmet shell, densely etched wave patterns, fine nautical linework inside the visor. Crimson, cobalt blue, warm ivory and black. Bold geometric circles and diagonal panels, strong contrast between the monumental helmet and the miniature world within it, vintage screen-print poster, no photorealism, no 3D.
