This started out as a simple illustration of a prehistoric jungle girl climbing up some branches emerging from the jungle canopy. To give her a more specific identity, I modeled her knife after the distinctively elongated stone blades of the Lupemban industry, a Middle Stone Age lithic industry that spread across the Congo Basin in central Africa over 265,000 years ago. The people behind this culture would have been either early Homo sapiens or a related hominin species.
