#17. Street Photography- Two photographers, Helen Levitt and Martha Cooper, took to the urban streets to capture kids at play. The photo (above) was taken by Levitt in 1939. The photo (below) was taken by Cooper in the late 1970s. Though the images are separated by forty years, the kids remained pretty much the same- roaming freely whole city blocks far from home and parents. They also made creative use of abandoned buildings and chain link fencing to test their courage and climbing skills. Interesting, too, that neither photographer bothered to tell the kids to get down.
