Vancouver Biennale. Miss Mao Trying to Poise Herself at the Top of Lenin`s Head is a public art installation depicting Russian Communist leader Vladimir Lenin and a feminized Chairman Mao Zedong in the heart of Richmond`s business district. The large stainless steel sculpture was created by Beijing-based brothers Zhen and Qiang Gao. Their highly political installations, which include provocative depictions of Chairman Mao, are sometimes shut down by the Chinese government and their studios have been raided. The statue, installed in front of the Insurance Corporation of B.C., aroused a lot of debate in the press and blogs. The Vancouver Sculpture Biennale, takes place every two years featuring public art works by about three dozen artists from around the world. Biennale sculptures are typically removed within two years.
