Given to a German industrialist about 1910, subsequently sold by his heirs in Amsterdam in the 1980's. The collection comprised mounted spears, spear heads and other a few other items. Each spear head finely forged with black scale surfaces opposite bright "white" surfaces laboriously polished by slaves. We sold over 50 fully mounted examples matching these but for the hafts, at $500-$1250.00. They sold out based on their ranking among the finest on the market. This example, 15 1/2" length with leaf shaped blade of offset section, the bright faces with uniform angled stone polish, each impressed with two elongated crescents. Opened seam conical socket decorated with a five line band on each end. Excellent with good patina.
