Fun! I was surprised how often I was 1 year off and in the right city for things that I was just guessing about.
On small error I found: there's a photo that's outside Piazza Navona in Rome in the 30s, which it lists as being 700 meters away at Piazza Venezia. I know I'm correct -- I lived a street away from there.
Maybe it moved 700m since the 30s? =)
