This vintage, retro-inspired design recreates the look of an old-school natural history textbook, featuring a detailed Cretaceous Period dinosaur landscape with Stegosaurus, Triceratops, a large theropod, long-necked sauropods, volcanic peaks, and prehistoric vegetation. Printed in earthy brown and tan tones against vibrant shirts, the distressed textbook-style artwork gives this science tees an authentic 1980s educational aesthetic. Made from 100% ring-spun cotton (high-quality cotton) with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
