This vintage natural history tee features a blue line-art Parasaurolophus with a frog perched on its back, printed on a clean white shirt for a soft field-guide illustration look. The design references the Late Cretaceous Period, highlighting the distinctive crested hadrosaur Parasaurolophus alongside a whimsical amphibian companion in a retro scientific style. 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.
