http://en.wikipedia.org/wiki/Clarence...

Clarence William Anderson (1891–1971) was an author and illustrator of children's books. Known professionally as C.W. Anderson, Anderson had an interest in horses and drawing.

Anderson started his career by illustrating for other authors, but eventually began developing texts to accompany his realistic and lively black and white drawings. He is best known for his "Billy and Blaze" book series.

The adventures of Billy and Blaze would revolve around proper care of the horse, while teaching a lesson. Anderson would go to great lengths to give accurate information. He would even go on to write Heads Up, Heels Down as a training tool for young horse lovers. All of the stories Anderson wrote would be based on true stories or people that Anderson knew, only the plots were fiction.

By the end of Anderson's life, he had written and illustrated over thirty-five horse books, and also had created covers for the Saturday Evening Post.
