IF you look carefully you can spot the ball on this atmospheric photograph.

It can just be seen against a strut of the central gas holder. The photograph was taken on the recreation ground at Spa Road, near Queen's Park, but I can only guess at the date.

I would say it was taken in the 1960s or 1970s, but I am conscious that I have been hopelessly wrong in the the past.

It is probably a school group - that looks like a teacher at the back - but I have no idea which one it was. Can anybody tell me?
