The Sao Paulo Art Biennial may be renowned for celebrating the best of Brazil's avant garde, but international critics say one of this year's featured exhibits -- a series of charcoal sketchesdepicting the imagined assassinations of former U.S. President George W. Bush and Queen Elizabeth II, among other world leaders -- has gone too far. (Scroll down for photos)

One sketch in the controversial series, titled "Enemies," depicts Bush kneeling on the ground while artist Gil Vicente presses a pistol to the former president's temple. In other sketches, the Queen is apparently unaware of the artist pointing a gun directly at her back, while Pope Benedict XVI faces Vicente directly, his arms outstretched in a quizzical shrug. Other world leaders shown in Vicente's 9-sketch series include former Israeli Prime Minister Ariel Sharon, Iranian President Mahmoud Ahmadinejad and Brazilian President Luiz Inacio Lula de Silva, according to The Telegraph.
