Boppard's 1921 notgeld issue was handled by Gebrüder Parcus, a Munich firm that printed a substantial volume of municipal emergency currency during the postwar inflationary period — they were a go-to house for smaller Rhineland towns that lacked local printing infrastructure capable of producing secure paper currency.

Boppard itself was under Allied occupation at the time of issue, the Rhineland having been placed under French administration following the Versailles settlement. Whether that complicated the authorization and distribution of this note is not documented in the standard references, but the political circumstances of the issuing municipality were anything but normal.
