Sun variant: rays as radiating pine boughs. The real Pentaceratops (say it PEN-tah-SERR-ah-tops) lived in the Late Cretaceous — carried one of the largest skulls of any land animal ever. Drawn as clean flat vector shapes in a fixed six-ink palette, mid-century poster style; edges stay razor sharp even at the six-inch size. Matte vinyl with a protective laminate — it survives water bottles, dishwashers and about three years of direct sun.
