Found a posting of some fabulous old photos (1940's-1960's) of Downtown Chicago. Most of these don't seem to be art pics, but rather snaps of the city. Taking a quick glance through them I could find no obvious plane trail lines like you see today. Some of the skies show smog from industry, but no 21st century plane muck-ups, as far as I can tell. My own photos of the downtown area in the 1990's also have no plane lines.
According to the idea that the more airplanes in the sky, the more contrails you are going to see, I would think that by the 1960's contrails would show up frequently in photos, but none here.
