On Thursday I got a postcard from Estonia.
It shows three sights of Tallinn including the Estonian Maritime Museum (lower picture). The Estonian Maritime Museum was opened in 1935 and focuses on the history of ships and navigation in Estonia. It is housed in the Fat Margaret tower of Tallinn's medieval city fortification.
With a nice stamp:

Thank You very much Jaan!
