Why the title? Well, it will make more sense in the upcoming exhibition, where there'll be a painting of the same lady with a cat mask. Also, in this particular drawing she seems perfect, too good for us normal folks - it is not quite clear in the drawing, but the make-up and hair is professional level.
My husband asks me why would anyone want to look at the back of a head but I do feel drawn to painting them - that character can be shown this way, without the distraction of momentary moods. After all, the back of the head shows us posture and hair, both of which tend not to be a short term appearance but a reflection of our more long term ideas about ourselves.
