Marking 75th birth anniversary of noted artist Hashem Khan, a celebration programme was held on April 16 at Bangladesh National Museum. The event also featured launching of two books -- “Kotik”, a novel on Liberation War by Hashem Khan and “Hashem Khan-er Kaaj” by Burhanuddin Khan Jahangir. Hashem Khan, on his five-decade art career, has played a significant role in every democratic and cultural movement of Bangladesh.
