Description and research notes
Issued 50 Złotych banknote of the Narodowy Bank Polski dated 1 December 1988 displaying a major typographic omission error. The entire printed layer containing the line 'WARSZAWA, 1 GRUDNIA 1988' together with the signatures of the issuing officials (Prezes and Główny Skarbnik) is completely absent. The national eagle emblem printed in the central guilloche remains intact, demonstrating that only the upper black typographic layer failed to transfer during printing.
The portrait depicts General Karol Świerczewski, a prominent military figure of the Polish People’s Republic era. The surrounding design incorporates a dense offset guilloche network and intaglio portrait engraving typical of late communist-period banknote production at Polska Wytwórnia Papierów Wartościowych in Warsaw.
Production of these notes involved multiple sequential printing stages. First a multicolor offset background and security pattern were applied, followed by intaglio engraving for the portrait and main denomination elements. Serial numbers were then printed in red, after which a separate typographic pass added the date line and official signatures. The present error indicates that the sheet either skipped the final typographic stage or passed through the press with an uninked plate, leaving the signature panel blank while all other printing layers remain complete.
Errors affecting the signature and date panel are significantly scarcer than ordinary color shifts or minor registration faults because they require a failure in the final stage of production after most printing operations were already completed. Such pieces provide valuable insight into the layered printing workflow used by PWPW in the late 1980s, immediately prior to the monetary reforms that would transform the Polish currency system in the following decade.
This example retains the original red serial numbering HK6400358 and shows typical circulation handling, confirming that the error escaped quality control and entered everyday use. As a result, it represents a rare surviving example of a dramatic missing-print error from the 1988 50 Złotych issue.
