Banknote with no deflection in the field.
Not very nice edges, especially the left one.
The edges bear no signs of later trimming, but the banknote in a very unusual format - clearly shorter, but at the same time taller!
The format of the present 165 x 87 mm, the catalog Czeslaw Miłczak gives 170 x 83 mm for this denomination. There are minor discrepancies from these dimensions, but this one is definitely oversized.
The printing does not raise suspicions about its originality.
