Entitled Umshini Wam, the painting is on display at the AVA Gallery in Cape Town, The Star reports.
It is part of an exhibition called ‘Our Fathers’.
The exhibition also has other works of artist Brett Murray whose controversial painting, The Spear, resulted in protests against Johannesburg’s Goodman Gallery in May.
Mabulu’s painting is priced at R75,000.
“He is not naked; I did not paint him with an uncircumcised penis. This is a metaphor that shows he is not a boy; he is a man, an elder, a father, a leader,” Mabulu was quoted as saying.
“In this painting I’m engaging my elder in the language of my mother tongue, the language that carries the culture of my people, the language he understands the most.
“Through this painting, I respectfully, as one of his children, ask my father why he is starving us. Why he is negating his duties to his children, the citizens of South Africa.” Sowetan
