Mural art does not require artistic training to understand the artist’s intention. For instance, more than lengthy English texts about the proletariat revolution, mural art in the street where it was open for the mass to see was much more effective to send the message. In the case of Diego Rivera, one of the three big Mexican muralists painted about the working class and where the Mexican public should be headed after the Mexican revolution in the 1920s. The mural above is “Man, Controller of the Universe”. It shows a man in the center and an omnipotent hand which seems to be in control of background paintings that represent different industries and studies: agriculture, biology, politics, and mechanics. This mural gave the Mexican public a sense of goal and responsibility for what they must make in the upcoming future of Mexico after the revolution. This and many of Rivera’s other mural art was able to move the mass to agree with the administration after the revolution. Even in entirely different forms of art, entertaining movies cannot possibly be compared its value to a movie that carries a clear message and inspires people.
Mural art has a function and a message, which is what makes the art valuable no matter where it is or who did it. Banksy is unarguably the most famous street painter in the world, yet anything about him is known other than the fact that he is based in England. His paintings are on the back of a shop or an alley where many people to see and his paintings always have a clear message, often politically- charged. In 2016, Banksy’s Les Miserables inspired piece appeared near the French embassy in London. It presented a young Cosette crying because of CS gas. In the left bottom corner, Banksy also printed QR code, which allowed people to see footage of French law enforcement firing tear gas at refugees in Calais, France. Banksy wanted to raise awareness of what had happened in a refugee camp in Calais to raise awareness, criticize and most importantly report to the global audience what an injustice occurred in Calais. He utilized icon of Les Miserables poster, Cosette and French flag fluttering in the background to signify French injustice.
