Czeslaw Miłczak mentions in the catalog the existence of zero-numbered samples, but only as single-sided prints. As a full double-sided print to our knowledge it is an item not recorded so far.
Technological acceptance with zero numbering printed on paper without watermark.
Item probably already from the final stage of preparation for production. Printing consistent with the final accepted, although the color scheme slightly different, warmer.
Slight callus in the lower part, behind the portrait. Otherwise state of preservation without remarks.
Most likely a unique one!
