The Director of the Design Museum in London has written a book about what makes a Warhol a genuine fake; the creation of national identities; the mania to collect. It’s also about the city as seen from the rear view mirror of Grand Theft Auto V; digital ornament and why we value imperfection. It’s about drinking a bruisingly dry martini in Adolf Loo’s American bar in Vienna, and about Hitchcock’s film sets. It’s about the modern world of fashion, technology, design and art. Chaired by Dylan Jones.
