From the moment I first saw it, some 20-odd years ago, Union Station on the edge of downtown L.A. became one of my favorite buildings. Walking through it makes me feel like I’m on a movie set—probably because it’s so pristinely maintained. It opened in 1939, but it could have been last week. Judging by the cars, I’d say this shot is from the 1950s, but on the other hand, the sky looks suspiciously smog-free, doesn’t it? The brown car is a 1948 Plymouth 4-door sedan, and the tan one is a 1949 Chevy Deluxe coupe, so this photo is probably circa 1950.
