Rare Moomin

Just found this Moomin artwork. I've never seen it before, so I guess it's pretty rare? It was a loose supplement to an issue of Lajban (a Swedish paper for kids) in 1970. Guess most of these were cut up and played with back in the days, so I'm thankful that at least one kid ditn't bother to play with it. :-)  Signed by both Tove and Lars. Enjoy!
