A months-old feces smear — or should we call it a fresco? — on a block of Russian Hill is now a work of public art thanks to a small museum-style label, likely placed there by a big fan of Marcel Duchamp.

According to the tipster who sent these images to SFist, "the people who live there haven't bothered to clean it up, even though one of the condos just sold for $2 million." Who cares about the condos — what's this piece selling for?
