A South Korean man looks at a painting portraying Park Geun-Hye, the presidential candidate of the ruling conservative New Frontier Party, giving birth to her own father and late strongman Park Chung-Hee, at a Seoul gallery on November 20, 2012. South Korea's ruling party has threatened to sue the left-wing artist Hong Sung-Dam who painted its presidential candidate giving birth to her father, former dictator Park Chung-Hee, likening the work to Nazi propaganda.
