I read once that the Frog and Toad books by Arnold Lobel are the finest I Can Read books ever written. You'll get no argument from me.
The discovery of an early Frog and Toad book is wonderful news. Even if this frog and toad are not exactly the Frog and Toad we've known these thirty years or so, readers who love them will appreciate the opportunity to see how they evolved.
Perhaps this book will show us Frog and Toad in a tadpole stage.
