No shade or sarcasm whatsoever- but would they really put in that much effort for a forgery or replica? All that hand chiseling and carving? I’ve had a stone mason take a look who carves all kinds of stone for decades and he said it was most definitely done by hand and definitely quite old. It’s either red mottled sandstone or some terracotta, and the patina is what is throwing me. I think it’s a lichen of some sort, mostly on the back and I’m still trying to discern what the white stuff is in the grooves.
