Roberts (1941-2016) specialised in straightforward Welsh scenes of stone cottages or rugged cliffs and seas.
Born in Anglesey, he moved to Croydon in 1962 to teach art and study part time at Croydon Art College before moving back to Wales in 1974. There he worked in local government and education.
Though he did not exhibit his work for many years, he continued to paint and devoted himself to it after retiring in 1996. Successful in his time, his work is now held in public and private collections internationally.
It was while clearing out his studio recently that Sue came across a sketchbook filled with the pictures he had completed during their drives.
These works on paper were studies for oils and larger pictures, and they are offered at the Oriel Tegfryn gallery in a show running from August 18-September 2.
A small number of larger paintings are also on offer, though most of the oils were sold during Roberts’ lifetime.
