This photo from 1951 gives us a clue about the scale of the Easter Fair in Blackburn, one of the social events of the year for the town back in the day.

The fair would pitch up on the Market Square - essentially opposite Marks and Spencer today.

You can only see part of the big wheel and the helter skelter which shows how large they were.

It’s interesting that the picture is credited not to a Northern Daily Telegraph photographer but to the Blackburn Borough engineer’s department.

Perhaps it was taken to record the structures and to study how much space the fair took up.
