Dangeorus forgery of one of the rarest Polish banknotes. Made on handmade paper with chemical security sign properly reproduced. The front side does not raise as many objections as Malinowski signature on the back that is much thicker and less carefully made than the original. There was a similar example described as original at foreign auction and it was sold for several thousands zlotys. There is a theory that assumes that this forgery comes from the same workshop as fake Polish specimens, often assigned to Kaminski.
