Eating a pickle under a rising sun. The real Chasmosaurus (say it KAZ-moh-SORE-us) lived in the Late Cretaceous — its enormous frill was mostly two big windows of bone, keeping it light. From the Sunrise Flats series: the same poster world redrawn in six flat inks — vermillion, pink, marigold, teal, indigo and cream — so it reads clearly from across a room. A reliable gift for the dinosaur person in your life: matte vinyl, waterproof laminate, three sizes up to six inches.
