I have a Lower Paleolithic Acheulean bi-face hand axe likely made by Homo erectus. My father-in-law brought it back from Libya when he was working in oil fields in the late 1970s or early 1980s. I had it assessed by a lithic-specialist archeologist from the Witte Museum in San Antonio, Dr. Harry Shafer, who wrote a nice little report on the piece.
