20 Korun

This 20 Korun note belongs to the first wave of Czechoslovak currency issued after the state declared independence in October 1918. The Ministry of Finance, rather than a central bank, was the issuing authority — because no such bank yet existed. The new republic needed circulating paper almost immediately, and these early notes were essentially a stopgap while institutions were still being built from scratch.

The adhesive stamp was the mechanism by which Austro-Hungarian banknotes were converted into Czechoslovak currency during the stamping operation of February–March 1919, but P#2 is a purpose-printed domestic issue, not a stamped-over Habsburg note. The security feature listed refers to a different kind of validation stamp applied to authenticate legitimate notes during that same chaotic transitional period.
