We see families splashing about keeping cool while making the most of the sun during the summer of 1969 at Sleaford Swimming Baths.
Behind the scenes there was a 2,900-name petition led by the Quarrington Young Wives group calling for the baths to be heated and have a roof.
Can anyone spot themselves taking a dip?
Continuing with the swimming pool theme, we featured a photo from the same year of construction work under way on a new pool for Kesteven and Sleaford High School. Elaine Wells contacted us saying: “The pool was built the year I started high school and we used it all the time I was there. I left after sixth form in 1975, it was fantastic for its time.”
