Joining the ranks of characters who live on long after their creators has passed away, it's The Cat in the Hat!
Here, you get to see the cat, Thing 1 and Thing 2, and the two kids as they explore the basics of flowering plants. The prose is at an appropriate level for kids who like the longer Dr. Seuss books. The illustrations (by Aristides Ruiz) are so close to the original that I couldn't tell the difference.
The only minor quibble is that the words don't flow QUITE as well as Theodore Geisel's words. Then again, few writer's words do. Also, Ms. Worth is faced with trying to teach a subject and entertain at the same time. At that task, she succeeds admirably.
