Sweden. Courier mail. Beautiful and rare courier letter to KRISTINA (1626–(1632)–1644–1654), Queen of Sweden with 6 rows of titles. With notation on front that it had arrived to the court-martial (Krigsrätten) June 15, 1636 and by who. No letter content. The little nice red seal on back with initials "E B" could lead to the sender. Good quality.
