Gagosian’s specialty is modern and contemporary art, but the location of the gallery’s new boutique in London dates to the Regency: it’s the Burlington Arcade, patrolled by Beadles in top hats and livery since 1819. The “original” department store off Old Bond Street is Mayfair’s junction of art and luxury, where gleaming handbags give way to the Royal Academy of Arts. Gagosian’s shop teems with rare books, prints, and objects. Like the art world itself, it balances on the cliff-edge of commodity, offering Damien Hirst tote bags, candles à la Keith Haring, and plates featuring works by Alexander Calder and Basquiat. Rotating upstairs are exhibitions and pop-ups, with photographs from Cy Twombly currently on view. Downstairs, the tomes and coffee table books stun. Millicent Wilner, a director of Gagosian, has called the shop “jewellike,” and it is, with many facets and wide Burlington window fronts that catch the light, and the eye. —Grazie Sophia Christie
