Forgery from the time of circulation not caught in the era.
With respect to the original , the color scheme isnoticeably different, in this case primarily too bright pink. The perception of the portrait is also definitely different, here too contrasting and exaggerated, and at the same time with simplifications.
An interesting theory regarding the damage to this piece was presented by Jakub Zalewski, who delves into the subject of counterfeits of Polish paper money. In his opinion, these are intentional damages - tears, rips, etc. - performed by counterfeiters to disguise the natural wear and tear of the circulation, and thus mask the imperfections of the reproduction of the original. To cast the noticeably different visual perception of this banknote on the canvass of circulation wear. This theory seems very plausible to us.
Interesting item.
