The oil painting of rugby legend Shane Williams unveiled today is the work of Welsh portrait artist David Griffiths.
David was brought up in Pwllheli but later moved to London to train at the Slade School of Fine Art.
He is well-known for his painting of the Prince of Wales receiving the freedom of the city of Cardiff in 1969 - the year of the Investiture.
He has since depicted many public figures, including Enoch Powell and the Archbishop of Wales, Barry Morgan.
Shane Williams is not the first sportsman to become the subject of David's paintbrush - Joe Calzaghe, Jack Matthews, Bleddyn Williams and Barry John have all been captured on canvas by the Welshman.

I am looking forward to seeing Shane again and am delighted that he can unveil the portrait.
He is indeed an iconic sportsman and it was a pleasure to work with him.

This portrait has a real sense of presence.
We feel as though Shane has just walked in and will be ready in a moment to play another game for Wales.
Wales' all-time leading try-scorer Shane Williams will unveil a portrait of himself later at the National Library of Wales.
The portrait, which was painted in oils on a 30 x 40 inch canvas over a period of six months, depicts Shane wearing his kit for his last international match against Australia in December 2011.
Welsh portrait artist David Griffiths, who has depicted many of the UK's public figures during his 40-year career, painted the sportsman last year.
The painting has joined other Griffiths portraits of eminent Welsh figures in the Aberystwyth-based National Library collection.
