Zainul Abedin was still in his twenties when he made these drawings - some of the originals are in the British Museum, whose website records that Ela Sen's book was banned by the British authorities, presumably because of its impact on wartime morale. There is no doubt that British alarm about the prospect of a Japanese invasion of Bengal from Burma - and so their determination to ensure that stocks of grain and boats for river transport couldn't fall into the enemy's hands - contributed to the scale of the tragedy.
In the 1940s, both Zainul Abedin and Sobha Singh had links to the progressive writers' movement, and were clearly on the left. Abedin has come to be regarded as the founding father of modern art in Bangladesh. He died in May 1976.
