"I had only the germ of an idea for Lentil. It started out as just a lot of pictures of a boy playing the harmonica. I didn't have any idea whether I was going to have words with my pictures or not. I thought the drawings might lead to a series of lithographic prints, not necessarily to a children's book at all. But once there got to be some words, the words grew and then the pictures grew."~ Robert McCloskey, children's book creator, in an interview with Leonard S. Marcus as collected in "Ways of Telling: Conversations on the Art of the Picture Book", page 109.
