Sir Kyffin was known for his "brooding" landscape images

Sir Kyffin, 88, who was Wales' foremost artist, was renowned for his stark paintings of the north Wales landscape.

At an auction in Chester, two of his works, described as archetypal "brooding" images, sold for �75,000.

Picture specialist Richard Hopkinson said it was interesting to see how prices for his work were affected.

Both works, Sunset Rhoscolyn and Road to Maltraeth, described as "archetypal Kyffin Williams - brooding, slate-grey Welsh landscapes most likely painted with the artist's palette knife" were bought by Welsh buyers and are set to stay in Wales.

Sir Kyffin Williams' work has consistently fetched strong prices over the last decade or so and it would be great to see this trend continue Richard Hopkinson, Bonhams

Sunset Rhoscolyn, an oil on canvas, sold for �47,350 at the Bonham auction. The record price for a Williams work is �48,000 achieved in November 2005.

Road to Maltraeth a slightly smaller oil, achieved �27,612 in the auction, more than double its pre-sale estimate.

Sir Kyffin died at an Anglesey nursing home on 1 September after suffering from lung and prostate cancer for some time.

Examples of his work are held at Government Art Collection, Arts Council of Great Britain, National Museum of Wales, National Portrait Gallery and Walker Art Gallery, Liverpool.

Anglesey Council has called for a national gallery to house his works to be sited on the island.

Richard Hopkinson, of Bonhams, said: "It was always going to be interesting to see how the prices for his work have been affected.

"Although it is too soon to tell, we are delighted that the paintings in the sale have made more than double their estimates.

"However, this is mainly due to both being fine examples of the artist's work, both with very good provenances.

"Sir Kyffin Williams' work has consistently fetched strong prices over the last decade or so and it would be great to see this trend continue."
