Andy Warhol muse Jane "Baby Jane" Holzer sold her penthouse at the Volney on the Upper East Side for $14.1 million. But maybe she should have held onto it for a few more years. The buyers, according to the Journal, just resold the place for $17.5 million. Tactics that may have helped: decorating the place with pop art?and making it look like a major bargain. The sellers first listed the place for $23.5 million last year, but the price fell all the way to $18.5 million before a buyer came forward. We're assuming that buyer?identified only as a fund manager?has no plans for another flip attempt.
