Do you recall poring over the pages of magazines (Life, Look, National Geographic) and learning to see the world? Two articles on the web sites of popular news magazines show stunning color pictures of the past.
Newsweek has a slide show, In Revolutionary Color, depicting Russia in 1907-1925. The portraits are so vivid they still seem to be living people.
Time has a slide show, The FSA and the Dawn of Kodachrome, showing color scenes of rural workers and labor migrants in the 1930s. You may glimpse parts of Illinois, before your time.
