The Royal Academy of Arts runs some museums in London, and elsewhere. In 2008, they did an advertisement so that more people would visit their museums. In this advertisement, they showed a picture of a naked woman. This painting was done by Lucas Cranach the Elder in the 15th century. It is called "Venus" (shown above). The picture was printed on ads in the London Underground. It caused protests in London. Because of the protests, Transport for London refused to allow the ads to be used in the Underground. On December 7, 2008, the Internet Watch Foundation put the Wikipedia article on Virgin Killer, on their blacklist. This meant that most Internet users in Great Britain could no longer access the article. The foundation did this because they believed the original album cover could be child pornography. The cover is pictured on the Wikipedia article. It shows a naked ten-year-old girl in a sexual pose, with her breasts shown.
