I want a nice picture book with 12 pictures - I do my best with that format.

I did about 2000 covers altogether, for all sorts of books - from Shakespeare to James Bond - and I always had the idea that I must give 100%, no matter who the author was.

I thought it was amazing to work with authors, to get a manuscript and try to make up a cover for it.

Then one day I thought it would be wonderful to make a whole book, to make my text and my drawings together, and that's how I started doing children's books.

Each book first begins with a little idea.

When I make a book, I make it for the child and not for the parent - no jokes in it for the parents!

My father realised that for me to become a publisher in his firm would have been the end of the firm!
