These Illustrations have been made on various concepts. 3 of them depict Krishna metaphorically telling the world about a humane feeling. One with his music, other with a war horn, and the third with his weapons. The music depicts all the small things in one's life which bring happiness to oneself and the world around, war horn depicts a war which mankind has to take up against deforestation and pollution, and lastly the weapons showcase how every man has a battle to win all the time. The most peaceful has sometimes to be the most destructive to achieve the end and to take up a stand. 
Ram has been showcased as a battle hardened person, who has to pick up his weapon for his righteous nature.
