(John) Wesley Dennis was an American illustrator best known for his collaboration with author Marguerite Henry, with whom he published 15 books.
He illustrated over 150 books in his lifetime, including Anna Sewell's Black Beauty and John Steinbeck's The Red Pony. He also wrote and illustrated a few books of his own, among which are Flip, Flip and the Cows, Flip and the Morning, and Tumble.
Tumble the wild mustang is introduced, and then half the book is immediately given over to a brief history of horses in North America before coming back to Tumble and his capture by men who put the spirited steed in a rodeo as a bucking bronco. Tumble yearns to be free and jumps at the first chance that comes along.
With only a sentence or two per page, this spare and barely there tale is like a precursor to Spirit: Stallion of the Cimarron and only takes a couple minutes to read.
This is a cute little book bordering on sweet about a very lucky lucky (and incredibly cute) mustang named Tumble. Wesley Dennis is best known for his work on Marguerite Henry books and it shows here. Tumble looks more like one of his Chincoteague ponies than a mustang (although mustangs can be quite small.) The pencil illustrations are the best parts of the book. See?
The text is for first graders and unfortunately does contain a factual error about mustangs. The lead mare finds food and water for the herd, not the stallion. I'm not sure if this fact was known in 1966. Also, you have to wonder how a mustang as small as Tumble managed to throw off full-grown men in rodeos. And why he was never recaptured -- but then, I guess that would have made the book too long for Dennis' target audience.
Still, recommended for horse lovers or lovers of pencil drawings. I bought a copy recently and consider it money well spent.
