A friend of mine bought the one that was on ebay. I go to see it up close and personal the other night. While the sculpt is great, the casting is very, very poor. Tacky, finger prints in the resin, air bubbles, the resin looks old as it's yellowed quite a bit. Just an all around poor job. And it's not even a full skull, it's flat on the back(I guess so if you want to mount it to a wall or set in on a table).
Don't waste your money. My dad knows a guy who's a pretty damn good sculptor. We're going to see if he can't sculpt this bad boy and we'll try our hand at some castings.
