The Finnish Postal Service now operating under the moronic moniker Itella, rather than Posti, as it was previously known (Itella apparently is more "international sounding"), has recently issued a new set of Moomin stamps.

The Moomins were created by Tove Jansson. Tove,who was from the Swedish-speaking minority population of Finland, was a painter, author, illustrator, and comic strip artist.

This particular television version of the Moomins was a Polish-German collaboration (Opowiadania Muminków in Polish, in German,Die Mumins) produced between 1977 and 1982. It was broadcast in the U.K. from 1983 til 1986.
