20 Markkaa, Litt B

The "Litt B" designation on this note reflects a deliberate administrative distinction within the 1945 series — Finland used letter suffixes to differentiate successive printings or authorized variants, a bureaucratic layer that becomes meaningful when tracking the volume breakdown across the series. At over twelve million pieces, this was a high-volume print run by Finnish wartime and immediate postwar standards.

Finland's currency management in 1945 was shaped by the armistice terms imposed after the Continuation War, including significant reparations obligations to the Soviet Union. Domestic printing capacity at the Government Printing Office in Helsinki was stretched across multiple denominations simultaneously.
