20 Gulden Bank Von Danzig

The Free City of Danzig maintained its own currency throughout the interwar period, a direct consequence of the 1919 Versailles settlement that detached the city from both Germany and the newly reconstituted Poland. By 1937, the political situation was deteriorating sharply — the Nazi-aligned NSDAP Danzig had won a near-majority in the Volkstag by 1933, and the city's institutions were operating under increasing pressure from Berlin. This note was issued into that atmosphere.

Bradbury Wilkinson's involvement is worth noting. The London firm printed for dozens of smaller sovereign and semi-sovereign entities precisely because they had no political stake in the outcome — a practical neutrality that made them attractive to contested or fragile issuers. The Free City's currency collapsed entirely in 1939 when Germany absorbed Danzig in September of that year.
