Firefighting is often a family affair with one generation following another into the service.
This is a portrait of Superintendent John Blyth of the London Salvage Corps, flanked by sons Herbert, on the left, and William, on the right.
The photograph - from the family archives - is believed to have been taken at the salvage corps station at Southwark Bridge Road, according to the Blyth's ancestors.
The salvage corps station - No. 3 - was located opposite the headquarters of the old Metropolitan Fire Brigade Station at Southwark and protected D District, which covered South London, according to Wikipedia.
