I bought this collection when I went to the Adventures in Moominland exhibition in January, and am actually a bit miffed - I should have spotted that it is not by Tove Jansson but by her brother Lars, and on checking inside it turns out to be the seventh of ten (so far) collections of the Evening News comic strips about the Moomins, of which only the first four contain Tove Jansson material. Next time I have a chance I shall try and get one of the earlier volumes.
This was my top unread graphic story on LibraryThing. Next in that list is The Autumnlands, Vol. 1: Tooth and Claw, by Kurt Busiek.
