A council is looking for people to submit their memories of the borough as they celebrate 40 years.
Hertsmere Borough Council was formed on April 1 1974 as a result of the Local Government Act 1972, bringing about a merger of the former area of Bushey Urban and Potters Bar Urban districts with Elstree Rural District and the parish of Aldenham, part of Watford Rural District. The district was awarded borough status by Royal Charter in 1977.
Leader of the council Morris Bright, said: "Our 40th anniversary year provides an excellent opportunity not just for a bit of fun and nostalgia but also to reflect on what has been achieved across Hertsmere during that time.
"The changes in culture, lifestyle and technology have certainly been quite breathtaking and residents who have lived in Hertsmere since 1974 will have seen a huge transition in the ensuing 40 years."
To mark the anniversary, the council would like see any old pictures of the borough from the past 40 years.
