Münster's 1921 municipal emergency currency was part of Germany's vast Notgeld phenomenon — a system where local governments and businesses printed their own small-denomination notes after the Reichsbank could no longer keep pace with demand for low-value currency. By 1921, the inflationary pressure was acute enough that even mid-sized Westphalian cities like Münster were acting as de facto issuers. Gebrüder Jänecke in Hannover was one of the more prolific commercial printers of this wave, producing Notgeld for numerous municipalities across northwestern Germany.
