Factual error: Fujiko is reading from a fictitious Italian newspaper ("La voce dei fatti") that reads the Japanese way, with the front page being where the last page would be in the Western design. Obviously no such publication could exist in Italy. That's also inconsistent throughout the scene itself, since at the beginning it is a normal left-to-right newspaper, then turns Japanese when Lupin says "You have a very discerning eye." (00:06:35)
Factual error: The police car license plates shown in the episode have a 2 digits-1 letter -2 digits pattern, while in reality they follow a different one (one letter and then numbers only).
