Sweden. Courier mail. Beautiful written courier letter to Admiral Erik Ryning at the Admiralty in Stockholm. Notation inside "Presented April 20, 1649". Erik Ryning was after the Peace in Brömsebro Aug. 1645 where Sweden got Gotland ordered by Queen Kristina to go there (October 1645) to receive the land on her behalf and let the population swear allegiance to her. Good quality!
