A clever little volume and pint sized- like Harold- contains the story of how he drew himself all over the place one evening with his purple crayon. Deciding to go for a walk in the moonlight, Harold draws a moon, then a path, and starts off. Then by mistake there's an ocean, a city, and more, until Harold wants his own window again and finally hits on drawing it around the moon. Johnson's picture are purple. You'll laugh at this. Good stitches.
