Mumintrollet: En liten present från Göteborgs bank: Föreningsliv

A single, standalone issue published in 1970 by Gebers, this Swedish-language comic presents a small gift from Göteborgs bank, focusing on the theme of "Föreningsliv" (club or association life) within the world of the Moomins. It stands as a unique, promotional publication tied to a specific institution and era, offering a glimpse into the beloved characters in a context outside their regular comic strips or books.
