“A picture book is not what most people think it is – an easy thing, with a lot of pictures in it, to read to small children. For me, it is a damned difficult thing to do, like working in a complicated and challenging poetic form. It demands so much that you have to be on top of the situation all the time, finally to achieve something so simple and so put together – so seamless – that it looks as if you knocked it off in no time. One stitch showing and you’ve lost the game”

Maurice Sendak
