A walking trail has opened in memory of popular Welsh cartoonist Grenfell Jones, who died in 2007, aged 72. Gren, as he signed his cartoons for the South Wales Echo for 35 years, created the fictional Welsh valley village of Aberflyarff. The proposed trail will wind its way around Gren’s home village of Hengoed and will include artworks featuring his characters and a green plaque at his birthplace.
