50 Markkaa, Litt. A 1918

The Litt. A designation on this note reflects a post-issue overprint applied by the Bank of Finland to distinguish notes in circulation during the chaotic monetary separation of 1918, when the newly independent Finnish state needed to differentiate its own currency reserves from those held in Russian-controlled or "Red" Finland during the civil war. Notes bearing the Litt. A mark were validated for use under the White Finnish government; unmarked or differently marked equivalents were not.

The underlying 1909 design was already a decade old by the time that overprint gave it political meaning.
