The New York Observer discovers that landmarks maven Barbaralee Diamonstein-Spielvogel and her ad-man hubby Carl (also, coincidentally, a big macher at the Metropolitan Museum) are selling their apartment at 720 Park, asking $37 million-or-so (representing a $17 million profit if they get their price). Which made me mirthful since Barbaralee chastized me when I announced I was writing a book about 740 Park, and insisted that I’d chosen the wrong building and should have picked hers. I wonder where the power pair will end up? (The story of 720 is told in 740 Park, by the way, and it’s quite amusing. Once upon a time, folks of the Jewish persuasion like the Spielvogels would not have been welcome there. L’shana tova, y’all.)
