Dig a little deeper and time runs backward. Beneath a pair of hiking boots in a wildflower meadow, this one-ink linocut in bone white cuts down through roots in the topsoil, wavy Paleocene beds and the thin K-Pg boundary layer that marks the asteroid impact 66 million years ago. Below that line, in Late Cretaceous rock, rests the skull of Tyrannosaurus rex, one of the last non-avian dinosaurs. The rock between the carved lines is simply the shirt, in any of its six colours. Made from lightweight 100% ring-spun cotton with a soft, sensory-friendly feel. Every order funds kelp restoration on the Pacific Northwest coast.
