Ottilia Adelborg (1855–1936) is another of the Scandinavian female artists who was an almost exact contemporary of the real (and the fictional!) Jeanette. She studied at the Swedish Royal Academy at the same time Jeanette was in Paris and may have studied in France later herself. She became a children's book writer and illustrator. The English-language edition of her Clean Peter is available online.
 
She also illustrated other writer's books, such as The Wonderful Adventure of Nils Holgersson by Selma Lagerlöf, for which this watercolor is a preliminary design. I haven't read the Lagerlöf book (which is available in a new translation), but this picture of a daydreaming boy and a tiny figure climbing out of the chest could suggest a story just by itself, don't you think? Or prompt a poem about the nature of imagination?
