This vintage-inspired design features a blue line-art frog perched on the horned head of a Triceratops, creating a playful natural history scene on a clean white shirt. Triceratops lived during the Late Cretaceous Period, and the lightly distressed retro illustration gives the artwork a classic field-sketch feel with soft blue tones. 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.
