Oh well, I could have just have posted all these three at once, but what the heck. Here's the third side (the front), depicting two wrestlers. I can't really remember the rules but reckon that they were a little bit harsher than today. It was either the eyes or testicles that were off limits.
The fourth side of this piece is un-carved - a reasonable guess is that it once stood up against a wall or in some other way that prevented the backside from being seen.
