Although controversial art is not a topic exclusive to the 20th century, the distribution of information regarding controversial art has increased with the proliferation of media. Please discuss an example of a 20th century controversial work of art from any discipline of the humanities (music, literature, sculpture, film, etc.) and an accompanying statement from the artist(s). Based on your example, to what extent does controversial art make a social contribution? Are governments ever justified in censoring art?
