In the defense of the mother, I suspect this is some kind of Chinese-calligraphy take on Andy Warhol. The examples look far too neat & clean to be real calligraphy, though. At least not the Japanese version of calligraphy. Slop & spastic incoherence seem to pass for passion & artistry in the work I've seen. I suspect this means that I don't "get" calligraphy.
