"Home on vacation in 1972, a photography student saw that the essence of his Welsh town was about to be torn apart by redevelopment. Now the social significance of his images has been recognised. Chris Arnot reports"
Came across this on The Guardian site. If you click on the "in pictures" to the right of the photo, there are some amazing pictures. I cannot get over the fact this was 1972 as it appears much older than that. Perhaps it's the black and white photography that does it.
