A rare and impressive printing error on the 1944 1 zloty.
The sheets were put into the printing press in reverse and the result was a full reverse of the obverse, relative to the reverse.
At the same time, due to the visual graphic similarity of the two sides of this banknote, the inspection did not catch this.
The banknote, with its extreme rarity, has been preserved in uncirculated condition.
Excellent item.
