Book 14: Herbert the Lion, by Clare Turlay Newberry, Smithmark Books 1998 (story originally published in 1931) Preschool to early elementary.
This book is an example of one that I bought for myself, before I was a mommy and before I was a children's librarian. About ten years ago I was intrigued by the wave of retro-looking illustrations that began to hit the bookstores, so I picked up this book that has older-looking illustrations, because it is an older story.
Having said that, this book should not be dismissed as only have reference value for those wanting to create retro-looking illustrations. The illustrations do propel the story, and improve it, but standing alone, the story is charming. And this book passes the toddler test.
