This hasn’t been a particularly great one for Indian art, except for one or two things like Zarina Hashmi’s retrospective at The Guggenheim. But the year ends with one great reason for everyone connected with Indian art to feel optimistic — the coming of Christie’s. Though Christie’s has had a sale of modern and contemporary Indian art in London and New York for many years now, its setting up shop in India is significant. Evidently, Indian art buyers are becoming a significant force and the world’s biggest auction house doesn’t want to miss out on the action. The only regret is that the exquisite paintings that Christie’s has brought together for its first sale in Mumbai have now passed into private hands, not to be seen again — until the next auction.
