A small but typical example: a key character in the book is a European collector of paintings, and when he first appears he has oily hair and an open silk shirt, exposing gold chains and a hairy chest (like the characters in Martin’s “Wild and Crazy Guys” skits). Later he is seen wearing an Armani suit. I have met hundreds of collectors in New York and elsewhere, and not one ever went about with an open shirt and gold chains or wore a suit that said Armani. Not one. The men tend to wear custom-made clothing, and in a range of styles of business attire. Other than the quality of the fabric and the stitching, which you have to look to see, rarely does it proclaim its high sartorial quality. It is not ostentatious, and it is not a recognizable brand. But with unintended irony, everything in Martin's book is a brand, a mass-produced badge of belonging to the elite.
