Next month, Tate Modern will host a stellar group show entitled Pop Life. Apparently, the show was going to be called Sold Out – a much more provocative and, some would say, apposite title, given that among the themes addressed by the curators is the notion of the artist as brand. Think Damien Hirst, think Jeff Koons, think, above all, Andy Warhol. Twenty-two years after his death, and over 40 years after his ascendancy as America’s most famous Pop artist, Warhol remains an influential figure on the making and selling of art. As his most obvious heir, Damien Hirst, puts it, “Warhol really brought money into the equation. He made it acceptable for artists to think about money. In the world we live in today, money is a big issue. It’s as big as love, maybe even bigger.”
