This is the Comet in Moominland (Kometen kommer) illustration AZ asked me to paint.
Tove Jansson’s illustration of this scene was once used on the back cover of an older edition, which was available in every English-speaking country except the U.S.
I just learned that (just now!) while searching for an image to post.
I also learned that there is a Moomin book that AZ and I have not read yet…apparently it is rare and out of print. It isn’t available at the public library, or on Amazon or Ebay. If anyone knows where I can find a copy, let me know! I’m too busy now to look into it much, but I’m sure AZ will want to read it eventually.
I lifted those images from Dusty Old Books. There are many more excellent images there, as well as reviews of old books.
