Estimated to be 16000 years old this is an image from the Lascaux Cave in Southwestern France near the village of Montignac. Four teenage boys discovered the cave in September 1940 and for about a decade the site was a major tourist attraction but the cave was closed to visitors in 1963 in an effort to preserve the fragile ecology of the cave. It has been a real struggle for the French to preserve the cave and its images intact. See The Cave of Lascaux. There is now an exact duplicate available for visitors. Most of the drawings in the cave are of large animals and most of the drawings are arranged in comic-strip fashion from left to right to tell the story of successful hunts.
