Donated by Rob Bradley. Rob writes, “Collapsed wall the morning after the September 1975 League Cup game v Stoke City that the Imps won 2-1. I was a surveyor working at the ground at the time assessing it for compliance with the new Safety at Sports Ground Act. The wall and supporters with it fell over at the South Park end while Peter Shilton was in goal. The club were quick to carry out all the safety measures throughout the ground after this happened!”
