Report: Lowry paintings of South Wales valleys on display

According to the song, the artist Lowry might have painted matchstick men and matchstick cats and dogs - but what's less known is that for years he also travelled to paint the South Wales valleys.

Now the first major exhibition of his paintings in London for almost forty years has put his largest works of Wales together for the first time ever. It opens tomorrow but ITV News was given a sneak peek, as Rob Shelley reports.
