Hello I recently received what appears to be a 1941 Polish bank note with Nazi stamps on it. One of the stamps says "Jude Warschau Waffen" on it. I have not bee successful in finding information online so this brings me here to this forum. I would very much like to know what the purpose of this particular stamp was for on these notes? If somebody with proper knowledge can offer an answer, it would be very much appreciated. Thank you.
