It is clear that the seller doesn’t know what this is. If I were selling it on eBay I would have noted that it was intended to have a candle placed in it, and that the light shines through the eyes and the crystal ball to great effect.
I’m thinking that the seller thought this was a particularly odd-looking sculpture, having a great big hole in it, and so was careful to take pictures that didn’t show its glaring hollowness.
