I have no idea who this is! The photographer, Theodore Waltenberg, was in business at the Bethnal Green address from 1890 to 1931 so I'm guessing that this photo was taken in the first 20 years of business. Can anyone narrow it down a bit more for me so that I can try to pin down some likely suspects as to his identity! The subject looks fairly young to me, late teens, early twenties?
The original photo is very pitted and faded any improvement would be very helpful.
Many thanks
