Hundreds of people gathered on Plymouth Hoe on Sunday to recreate a photograph from 40 years ago.
The flashmob-style event took place to honour the city's volunteers - just as it had on the same spot in July 1982.
New technology meant the new version picture was captured by a drone camera rather than by police.
It was organised by artists Hannah Rose and Rachel Dobbs, who work together under the name 'Low Profile'.
Rachel said: "Photographs like this are important to mark moments in time. Often volunteers can feel a bit fleeting and doesn't get marked in an official history, so we're really excited that this photograph will live on in different people's lives."
Larissa Milden, from Improving Lives Plymouth, said: "There are so many volunteers and organisations that do such great work in Plymouth that goes unnoticed, so it's great for that to be recognised today."
