The pandemic put a stop to one of our favorite things—a long day searching the stalls in a big antiques show, looking for that thing we didn’t know we needed. And what better place for the search than London? The Mayfair Antiques & Fine Art Fair is back after its pandemic absence. Chinese ceramics, enamels by Cartier, a Degas here, a diamond-and-platinum bow there. With some 35 specialist exhibitors on tap it’s not just shopping, it’s learning. —Laura Jacobs
