Controversial art

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?

(2)What were some of the influences of the pop art phenomenon? Should we consider the creative elements of popular culture, which are very often mass produced works of art?
