Why doesn’t Charlie have a face in the logo/illustration?

In reply to Ana, Joseph, Riley and Iman’s question:

You know I’m a book worm. I love reading but every time I sink into a book I’ve always found that my imaginings of the main hero/heroine never match the book’s cover. It seems, at least for me, that the artist’s interpretation never matched mine. So I was happy for all the other illustrations to have faces but felt it best that Charlie Keeper be left as just an outline so your interpretation of Charlie Keeper (and not the artist’s), will always be right .

All the funkiest,
