20 Markkaa, Litt. A 1918

This note was printed well before its 1918 issue date — the 1909 series had already been in production under the Russian imperial administration of Finland, when Suomen Pankki operated under significant tsarist oversight. The "Litt. A" designation distinguishes it from later lithographic printings produced under wartime conditions, as the newly independent Finnish state scrambled to establish a functioning currency after the January 1918 declaration of independence and the civil war that immediately followed.

The chaotic monetary situation of 1918 meant earlier-dated printing stocks were pressed into service without modification.
