Having grown up in the South during the era of segregation on the wrong side of the tracks, my own observations regarding these photographs and the method used to capture them, I would say that these were photographs of working people in their neighborhoods. I would also note that when I visited and lived in NYC, that there was a more complete actual segregation in NYC up through the late 50s, with huge areas such as Harlem, with large populations of black folks, and at the same time large areas with no blacks. Not legitimized as in much of the South, but still existed in reality. There was probably more social interaction between working blacks and working whites in those times in much of the South than in the North. The black and white working neighborhoods were separated but ragged and overlapping at the edges. As usual with NPR policies, no mention is ever made of which political party played, and still plays, the racial game.
