Back in the spring I found this box of glass negatives in Brick Lane market - the man who sold them to me (for £4) sells old tools, in a back-street part of the market that has been relatively untouched by the changes in the area.
My guess is that the family in the pictures were cabinet makers - a trade that goes way back in the East End, as one of the pictures seems to be of a cabinet in a work shop - this also goes some way to explain as to why they were being sold off with old tools, that looked like they had been emptied en masse from a works somewhere.
It was amazing to see the pictures appear on my screen as I scanned them into Photoshop.
