Minimal, slight and partial vertical overbend, basically invisible, only perceptible.
An exceptionally rare color variation of a fairly common banknote such as the 2 zloty 15.05.1946, which in the vast majority occurs in the correct green color assigned for this denomination. Here we have a very rare variety in blue.
Beyond any doubt, this is an original, period banknote, not subjected to manipulation, as was the case with the "blue" 10 marks 1940 Lodz Ghetto. You can read more extensively about the blue colors of the 1946 issue in a study by Mr. Pawel Pawlowski on portalnumizmatyczny.pl where the issue was discussed in consultation with Czeslaw Miłczak.
Definitely recommended, very rare and impressive value, originality guaranteed.
