Detail: Just over seven decades after the declaration of India’s independence in 1947 and the emergence of a modern art movement in India, Asia Society presents a landmark exhibition of works by members of the Progressive Artists’ Group, which formed in Bombay, now Mumbai, at a time of massive political and social upheaval. Spectacular works in the exhibition—primarily oil paintings from the 1940s to 1990s—underscore how these artists gave visual form to the idea of India as secular, heterogeneous, international, and united.
