Vesikko Submarine.

I received this card of the the Vesikko submarine through Postcrossing from Finland. This card has the picture of the submarine in an unusual angle!

Vesikko was a submarine of the Finnish Navy in World War II.After the war Vesikko was decommissioned because of theobligations of the Paris Peace Treaties that forbade Finland having submarines. Vesikko was lying as a wreck for years.The submarine currently lies on the island of Suomenlinna. It has served as a museum during the summers since 1973 as a part of the Military Museum of Finland. Vesikko is the last surviving Type II submarine in the world.
