Whaddayamean, by John Burningham, Crown Publishing, 1999.
I almost didn't pick this book up at the library some weeks ago. I thought the title was rather silly. The cover art, however, intrigued me, so I opened the book up to read it. Once I started reading this book, I could not put it down. I loved it so much, in fact, that I went out that day and bought a copy for myself.
This book is fantastic! And with this book, John Burningham has become one of my few favorite children's author/illustrators.
