Richard Scarry began his career in Children's books in 1949 with Little Golden Books. He penned and illustrated over 300 books but probably best known for his Busytown Series home to Huckle Cat and Lowly Worm. Have you seen the Busytown Mysteries series on CBS Saturday mornings? It's really great too! The cartoon illustrations are well, um, busy, packed with all kinds of detail on every page. Personified animals of every size fill the pages often the books have a find the 'gold bug' on them for added fun. Many books have the map of busytown in the front or back of the book too. I think that was one of my favorite pages to study when I was little.
Richard Scarry's Best Storybook Ever or similar collections of stories are a great way to go.
There are fun board books for the youngest of readers, like this title Cars and Trucks from A to Z where all kinds of zany cars and trucks can be found like Lowly's apple car.
As you can see Richard Scarry's books cover a wide arrange of topics, filled with delightful, well mannered (for the most part) animal characters. There's lots to learn and a good dose of silly fun to have!
