This retro, vintage-style illustration features a humorously anthropomorphic Tyrannosaurus rex behind bars, nodding to the Late Cretaceous period when this iconic predator ruled. Drawn in distressed blue linework on a clean white background, the playful sketch aesthetic blends classic science humor with casual natural history 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.
