Hello, Dinosaurs follows the style, format, and m.o. of Dwell's Goodnight Owl and Good Morning, Toucan. A question asked about a dinosaur's whereabouts is revealed via a turn of five die-cut gatefolds. Someone prehistoric is hiding in a cave, behind (really big) bushes, in the water, etc. Sturdy cardstock, spot lamination, and Dwell's signature palette and style give this book its decidedly upscale look and quality.
