When you say that half of those pictures were probably modern, did that include the ones that had Aztec or Mayan profiles as part of the design, or only the other fancy ones.
There were definitely some real artifacts shown but you would be amazed at the skills of modern knappers and their ability to replicate damn near anything they see. Their skills far exceed those from the past. To be honest I recognized the work of at least 3 well know knappers in several of those pictures and one older knapper who passed away many years ago, he specialized in Mayan eccentric style pieces and sold them as authentic. He was a complete fraud but much of his work is still out there and still being sold to unsuspecting buyers, he made thousands of pieces before he died. If FR didn’t require 3rd party hosting I’d show you examples of their work, I took the pictures myself.
