This is a two-pack special that includes the Dinosaur Sketchbook AND the SciFi Sketchbook. Both books are 34 page 6×9 paperbacks and signed by the artist. The SciFi Sketchbook contains drawings of robots, spaceships, weird intergalactic creatures, intrepid spacemen, and shapely retro-cool space vixens beating up horrid monsters. The Dinosaur Sketchbook contains, well, dinosaurs! All sorts of fantastical, made-up dinosaurs.
