Probably this shot is post-WW2 but perhaps it might be late 1930s given the profusion of London Transport trams, on their conduit system. The war had reprieved them as they soldiered on until final replacement in 1952 - the war had caused the plans to replace south London's trams with trolleybuses to be abandoned. As well as that - the detail - an old LT tram stop flag, and a fine close up of the local street lighting - ornate bracket and a GEC lantern. The timber shelter is a standard London County Council type - they ran the majority of tram services pre-1933 when LT was formed, and one still survives at Clapham Common.

Until about 1800 Camberwell was a farming village surrounded by woods and fields. The village was based around its High Street, now called Denmark Hill in honour of Prince George of Denmark, the husband of Queen Anne, who had a residence there. The village contained a traditional village green, which still exists, and it was here that Camberwell Fair was held. The earliest record of the fair is in 1279. It was abolished in 1855 as by this time it “attracted too many undesirables"
The image below is from circa 1800 depicting Camberwell Green. The location has persisted for nearly 250 years.
