This vintage, text-illustrated design features a classic black ink rendering of a sperm whale set against a background of printed script, giving the shirt a timeless natural-history aesthetic. Highlighting a species whose lineage traces back to the Eocene epoch, the monochrome artwork stands out on a crisp white tee for a clean, retro look. 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.
