Flying in the face of gloomy world politics, the art world was in high spirits on Wednesday at the opening of Frieze in Regent’s Park, where supermodels, including the German beauty Claudia Schiffer, and super-curators rubbed shoulders with the usual crowd of international artists and art enthusiasts. Purse strings were being loosened, too. Wissam Al Mana, the co-owner of Lazinc gallery and former husband of Janet Jackson, said healready had his eye on “a few pieces”. But by the end of the day, another fair-goer was overheard saying: “We might as well go to get something to eat; it’s not as if we can afford any more art.”
