Syd Hoff's Dinosaur Stories and More

From Syd Hoff, famed creator of Danny and the Dinosaur, comes this collection of three rare books:
Amy's Dinosaur features a forward-looking ecological theme. When Amy and her friends take a walk in the woods, they see lots of trash but no living creatures — until they meet a dinosaur who can't stand to see the Earth endangered once again and encourages the kids to help him clean up.
Dinosaur Do's and Don't's, a gentle and humorous primer on manners, advises children to get out of bed when mother calls, bathe without being told, ask permission to go out and play, say thank you, and engage in other polite practices.
How to Draw Dinosaurs, an easy-to-follow guide to sketching dinosaurs just like Syd's, features diagrams that show four easy steps to creating a stegosaurus, dimetrodon, archaeopteryx, triceratops, and other well- and lesser-known prehistoric animals.
