John Ronald's Dragons The Story of J. R. R. Tolkien by Caroline McAlister illustrated Eliza Wheeler*

This biography about J. R. R. Tolkien is the first picture book one I have seen.
Wonderful illustrations!
The biography mostly focuses on Mr. Tolkien's childhood with tidbits of him falling in love, going to war, teaching and beginning to write The Hobbit.
The author and illustrator offer additional fascinating facts on the "Author's Note" and "Illustrator's Note". 
*Highly recommend.
