An original color key concept from the Hanna Barbera animated series "Valley of the Dinosaurs" (1974). Featuring stunning rendering of a Brontosaurus strolling through a river, the hand-painted color key was created at the studio by well-known background artist, Paul Julian, and used during the animation process. The concept was used to develop and finalize the color palette, layout of the action, and the overall feel of the scene. When a color concept is finalized during production, it becomes the reference tool that animators use to paint cels and backgrounds, as well as to further progress through the storyboarding and layout of the individual scenes. Measuring 3.5"x5" overall, the concept is in very good condition with minor surface wear.
