“The American artist Jeff Koons has been found guilty of plagiarising an iconic French clothing advertisement for one of his celebrated sculptures, Fait d’Hiver. Advertising creative director Franck Davidovici had sued Mr Koons, among the world’s most bankable living artists, for copyright infringement, saying he had produced what his lawyer called a ‘servile copy’ of a famous advertising campaign he ran in 1985 for French clothing brand Naf-Naf.”
