Yes! Even movies from the 30s, b+w as they are, show us people 100 years back. Cities 100 years back. And a lot of that is now digitized, and kept by cinema lovers worldwide. We've always had to guess before, wonder, go by (comparatively) rare paintings, which may or may not have artistic changes. Even language has become more static, more uniform, starting with wide spread printed works, then radio, TV, now internet. If I look at works 100 years back, many of them could gave been written today. 150 years? Change becomes more rapid.
