I'm not really sure what this is. I'm aware it's an image of a lady, possibly naked, with her arm behind her head. But I'm not sure if it's a painting. Maybe it's some kind of photo-silver-chemical solution on the wall? Maybe it's graf, which is what people call graffiti nowadays.
Either way, it's very cool.
I'm writing all this from my phone as an experiment. It might look shit.
