A gentleman of Cymmer, Afan Valley.
I heard on 17th January 2014 from a Mr Huw Daniel, who grew up in Glyncorrwg.
He identified the man in the photograph as a Mr Hopkin. His dog's name was Mack.
Apparently he was a terrible practical joker and would give the children at Cymmer Afan school a poke through the railings with his stick as he walked past the school.
The picture was taken in 1976.
