It's never clear as to what an artist means to say when they present a piece of art: that's the point. Isn't it? We are meant to think, ponder, enjoy and perhaps feel frustrated.
Black face is offensive but I'm wondering if the artist is pushing a question rather than an idea. Is black face as offensive when painted onto a sexualized female image? If not, why is that so? Is the woman on her stomach the same woman who is sitting upright? It seems so. Does that make it any less offensive? Is it no longer black face if the black resembles paint that runs down the neck?
But does that mean the first image where we are unable to see paint running down her neck is meant to be the offensive image? Or are we meant to question the way we perceive the concept of racism. Is the first image no longer a black face image if we have decided the second image is not black face? Can we then ignore that we do not see paint dragging down the neck of the upright image?
