Brings back the echoes of childhood. That's why I like seeing stuff from the 40s or 10s, even the late 1800s, because people had them up when I was a kid. I was raised in the echoes of the past, both in decorations and the people who lived through it, and in some way I felt like I was part of it.
That's why I can only shake my head in bewilderment at young people today thinking they can recreate the past (*coughThirdReichcough*). By about the 1990s, all the ties to the past had been severed or under severe attack, and by the 2010s hardly anyone born had that kind of connection.
