Sun variant: sail sun. Dimetrodon (say it dy-MET-roh-don) is not a dinosaur at all: a sail-backed relative of mammals that lived some forty million years before the first dinosaur; it lived in the Early Permian. Sunrise Flats style: crisp geometric color blocks in six inks with a thick die-cut border — the minimalist cousin of our illustrated kaiju series. Cut to the silhouette on matte laminated vinyl: 3-inch fits a phone or bottle, 4-inch a laptop lid, 6-inch a notebook, cooler or wall.
