Part of what is written on that note translates roughly to "cast your ballot to ensure that the hyperinflation that happened in Lithuania, Hungary, and Romania does not happen here in Italy."
I don't know much more about this "note", but the page linked below seems to classify it as an "elezioni" (election) collectible, so presumably it is not a banknote at all but an election advertising handbill made to look like a banknote. The same page lists it with a price of EUR49.00.
