In which specific work D. P. Roy Choudhury used academic realism to celebrate the labour of the working classes?

Triumph of Labour

Answer: Triumph of Labour
In D. P. Roy Choudhury's work Triumph of Labour he used academic realism to celebrate the labor of working classes.

Ramkinkar Baij was an artist given to the celebration of nature. His art reflects his everyday experiences. Almost all his sculptures and paintings are created as response to his environment. For instance, his Santhal Family, made as an outdoor sculpture within the Kala Bhavana compound, turned the daily activity of a Santhal family setting out for work into a larger than a life size piece of art. Besides, it was made out of modern material like cement mixed with pebbles, held in shape with the help of metal armature. His style was in sharp contrast with works of earlier sculptor like D. P. Roy Choudhury, who had used academic realism to celebrate the labour of working classes, The Triumph of Labour.
