I saw this a way back, it does indeed look very dodgey. Resin casts probably cost less, and are better quality, and haven't potentially come from someone making a stand for human rights.
Resin casts also didn't used to be alive. Yuck, yuck, yuck. My gag reflex for death and decay is very shallow. :/ (decent reference though, I don't think I ever seen a male/female skull comparison in front and side views before. Leeching for the archives!)
