This is a single statue, sculpted with a demure woman in back and a confident man in front. The mirror allows the viewer to see both sides at once.
What I find interesting about this statue is how, despite the strange duality, the body languages of the man and woman halves seem so natural and normal. We expect feminine deference from a young pretty woman, and masculine stridency from a self-assured man, and that satisfied expectation balances our initial feelings of disorientation.
