Tat-ta Turner's Temple
J.M.W. Turner's The Temple of Jupiter Panellenius (1816) - a major oil painting worth as much as £10.6m ($16m) - is on display at Sotheby's in London until 4 December. It's doing the grand tour - Paris, London and Los Angeles - prior to being auctioned at Sotheby's New York in January. My guess is that this is the last time it will ever be on public view in the UK. (The current owner is American; the painting is merely visiting London and therefore cannot be blocked from leaving the country; and US art galleries have bigger budgets than do British ones.) So it's Tat-ta Turner's Temple.
