It was said that when her mother, musician Nora Back, died, Ms Johnstone refused to let the funeral directors transport her coffin. Instead she strapped it onto the roof of her estate car and drove it herself from London to Norfolk. Brett Tryner, director, Cheffins, said: “This is the final collection of pictures to come from Gwyneth Johnstone’s private studio and as such is completely fresh-to-the-market. Johnstone’s work is growing in popularity as her energetic and romantic landscapes become synonymous with East Anglian post-war art. "It was from the 1980s onwards that she saw her most success with a series of solo exhibitions in both London and Norfolk.”
