Tate announced that renowned art collectors and philanthropists Jorge M. and Darlene Pérez have donated a major painting by Joan Mitchell to the nation. This vast six-metre-long triptych, entitled Iva 1973, is now on display at Tate Modern. It can be found in the room adjoining Mark Rothko’s iconic Seagram Murals, enabling the public to see two of America’s greatest modern painters in dialogue with each other.
