Bank Polski contracted Hungarian Banknote Printing Company in Budapest for this series at a time when Poland's own printing infrastructure was still limited — the country had only re-established itself as an independent state a decade earlier, and outsourcing high-security work to established Central European printers was common practice. Magyar Pénzjegynyomda had the presses, the paper stock, and the intaglio expertise that Warsaw could not yet reliably replicate domestically.

Ryszard Kleczewski designed several notes in the broader Bank Polski output of this period. Rupert Franke's engraving work was well regarded across multiple issuing authorities in the region during the interwar decades.
