Tom Hoving makes a posthumous appearance on Page Six today with his new BFF and successor as Metropolitan Museum director Guy-Philippe Lannes de Montebello, who was known as Mr. Five Names when he ran an art museum in Texas. A nugget concerning Montebello’s appearance (above) at Hoving’s memorial early this month, it’s the first leak from the new afterword to the paperback edition of Rogues’ Gallery (out May 11).
