ENTERTAINERS Ronnie Wood, Mark Feehily (Westlife) and Brian Kennedy are among the 1,000 people who have contributed a piece of art to this year’s Incognito sale in aid of the Jack and Jill Foundation.

What makes Incognito so special is that prospective buyers have absolutely no idea who the artist is behind their favourite postcard-sized artwork until the collection has sold out, and the artists are revealed.
