Hazel Faithfull was a decorator of ceramics, based in Clerkenwell, London in the 1980s/1990s. She has now given this up and teaches yoga in Oxford. I used to meet up with her every year at the Little Venice canal festival and buy mugs from her. This is the last surviving one - handpainted then fired, with her monogram on the base.
Hazel also produced hand-painted tile scenes and bowls, etc...
