This striking natural history design features a Late Cretaceous Tyrannosaurus rex skull entwined with serpents, rendered in a vintage, lightly distressed illustration style that evokes classic fossil engravings. Printed in deep brown-black linework on a clean white shirt, the artwork blends paleontology with symbolic, almost mythic elements for a bold retro 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.
