From the opulent mansions of Fifth Avenue to the original interiors of Brooklyn’s brownstones, HBO’s “The Gilded Age” has brought to life a New York City lost to the demands of progress, changing tastes, and the march of time. The New York Metropolitan Chapter of the Victorian Society in America hosts a special evening with Bob Shaw, the show’s Emmy-winning production designer, to learn how he balances historical accuracy against creative license, the penchants of a modern audience, and the realities on the ground to resurrect nineteenth-century Gilded Age New York City. The talk will take place in the Veterans Room and Library of the Park Avenue Armory, designed by Centurions Louis Comfort Tiffany and Stanford White (who is responsible for the Century’s current clubhouse.)
