But we discovered that, although I liked publishing, the commercial side meant nothing at all to me.

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

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.

I have been drawing all my life.

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

I thought it would be very nice to become Picasso or Rembrandt, or a van Gogh.

I come from a family of business people, but I had the idea I wanted to become an artist.
