This is a striking mirror from about 1970 by the designer Anthony Redmile, the designer who ran a shop on Pimlico Road in London in 1960's and 70's. I think the shell is turtle, and the metal steel. The mirror is slightly smoked. It is heavy! I'm indicating 'collect in person', but you may wish to organise your own courier of course. I live on the ground floor and there is a large drive, so access is easy.
