‘The Ivy, Norwich’ by Colin Revell was chosen by Arnolds Keys, the exhibition’s sponsor, for its impressionistic style and “instant recognisability”.
Mr Revell, a carpenter and artist for 30 years, was selected earlier this year to appear on Sky Arts’ ‘Landscape Artist of the Year’.
His work frequently features recognisable Norwich locations.
Guy Gowing, managing partner at Arnolds Keys, said: “What really stood out is that Colin has absolutely captured this Norwich landmark, and yet in an impressionistic style which perfectly captures the movement and drama of a busy service on the restaurant’s terrace.”
The exhibition showcased more than 350 pieces from Norfolk artists, many of which were bought by visitors on the first day.
Tom Cringle, head steward of the Royal Norfolk Show Art Exhibition, said: “It is great to have so many amazing artists at the show representing the best in local work.
“We are very grateful for the public support both in visiting the exhibition and buying the artworks.”
