David Attenborough unveils portrait at museum he volunteered at

Sept 22 (Reuters) - British naturalist David Attenborough on Thursday unveiled a portrait of himself, commissioned for this 90th birthday, at the same museum where he used to volunteer as a teenager. The painting, by portrait artist Bryan Organ, is displayed at New Walk Museum and Art Gallery in the English city of Leicester, where a portrait of Attenborough's late brother, actor and film director Richard Attenborough, also hangs. Attenborough, who has travelled the world for decades making television documentaries, turned 90 in May. (Writing By Marie-Louise Gumuchian)
