(On May 22, 2012, this controversial painting of South African president Jacob Zuma (which depicts the politician, genitals exposed, in a dramatic pose reminiscent of Soviet-era poster work) was defaced while on view at Johannesburg’s Goodman Gallery.

One of the men, arrested at the scene, said simply, “The painting was offensive.”)
