Duality is the subject of this piece: female/male, anima/animus, yin/yang, positive/negative, black/white. Each illustrates two sides, and both sides of this piece are needed for it to stand. I further emphasized this duality by painting porcelain slip on the insides of both pieces in a hakami style, to contrast against the very rough outer backs.
This was a difficult piece. They are so powerful in inferred meaning that I found it necessary to give them a rather positive title, just to remind viewers that it could be positive.
