Mona Lisa's symmetry

She was known to the photographic investigators circles as "La Gioconda" because the man who was obsessively chasing her was convinced that she had a relation to the famous Leonardo's model… Of course his conviction was well established after years of investigations and the study of numerous family trees… I came much later to the case and my job was to take several shots of her while she was hanging around with friends in Europe. If you've asked me, I would definitely say that she had a resemblance with the most mysterious and intriguing female portrait in history. And there was also something else about her… She had a "symmetry" in all of her existence. The way she moved, the way she was standing, the way she was smoking. Her secret was well hidden under a "girl next door" attitude. But I knew. Did she? My employer never said…
