I received today, my LOR and photograph (unsigned) back in my SASE, however there was a pre signed photo included with a letter of apology from his agency, saying he didn't have time to sign but thanks.
My pre signed photo:-

The address of the agency that sent me the photo is:-
PBJ Management, 22 Rathbone Street, London, W1T 1LG
I'm happy I got an authentic autograph back, I do prefer to get the photo that I provide signed but the fact that I did get an authentic back has made me very happy indeed
