My apologies if this has been noted previously, but the link to the Daily Mail makes mention of the London photographer "Boris Bennett". If this name is Googled, his dates are given (1900 - 1985).
His collection of negatives over the years must provide quite a social archive of the Jewish community in London's East End, and it is possible that some organisation is now the custodian of these negatives/plates, and possibly record paperwork if these survived.
Googling the photographers name and dates, together with "archive" provided several "hits". The archivist appears to be a Michael Greisman (
http://www.jeecs.org.uk/news/92-boris-website-showcases-east-end-glamour) acting on behalf of the Jewish East End Celebration Society (
enquiries@jeecs.org.uk).
The same background in the "Dottle" photograph can be seen in several of the photographs in the Daily Mail article posted earlier today by LouiseB31. Whether this is a studio set, or an actual location is however a moot point.
Again my apologies if I am recrossing old ground.
