Manuscripts, Sweden. KARL IX (1550–1599–1611). Very interesting letter content about Magnus Wolfeldt's payment of interest rate for a property in Åbo (Finland). At this time Sweden had a newly started war against Russia. Very rare to document this. Dated Stockholm 16 August 1610. Signed Carolus with a complete royal paper seal still attached. One written page with transcript and also a postcard of the king.
