The Park Springs London overspill estate, Gainsborough. From the Lincolnshire Echo October 31 1969.
'Everything had changed. Mrs Paxton went to the small town and found another town had been clipped on behind it, with rows of houses and no shops. The people in the sudden new town were known as overspill. Mrs Paxton hardly looked at them, once she had left the butcher and the chemist, and had picked up her bread. If she had to pass by the boundary of these ghostly new streets she looked away, and the children and cats that played there were no more real to her than figures in a cartoon.'
