Older than the Museum of Modern Art and the Whitney Museum combined, and five years the Met’s senior, the Brooklyn Museum celebrates its 200th anniversary this month. To celebrate its landmark birthday, the New York museum is debuting a three-chapter group show, “Breaking the Mold: Brooklyn Museum at 200”—which opens this week. Organized by the museum’s Meghan Bill, the exhibition celebrates the borough's past, present, and future with works that span over five centuries.
