This clean, vintage-inspired design showcases detailed line illustrations of iconic marine mammals—including the narwhal, gray whale, sperm whale, bowhead whale, and humpback whale—arranged in a striking vertical layout. The crisp white artwork against the deep black fabric gives the tee a retro natural-history aesthetic while highlighting the evolutionary story of modern whales across the Cenozoic Era. 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.
