Sometimes when I'm shelving & pulling books at the library I work at, I come upon some real gems, like these two painters.
Zainul Abedin painted the suffering he saw in the famine in 1943, and was also a part of the Bangladeshi independence movement. The famine pictures are the first ones I saw. He was part of the Calcutta Group, the first group of modern artists in India.
Abanindranath Tagore has a more romantic style, lot of soft colors and traditional subject matter. Unfortunately I couldn't find many good images online, but the whole school of art he started, the Bengal school, has a similar aesthetic.
