IT DOES LOOK LIKE A GOOD OLD ONE AND PERHAPS COULD HAVE SEEN USE IN THE OLD TRADITIONAL WAY. THE THUMBS UP IS A FUNNY OBSERVATION AND THE LARGE WHITE DESIGN BESIDE IT EVEN RESEMBLES A THUMB. PERHAPS THIS TRIBE ONLY COLLECTED THUMBS INSTEAD OF HEADS LOTS EASIER TO CARRY WHILE RUNNING THRU THE JUNGLE ON THE WAY HOME WITH A ANGRY TRIBE'S WARRIORS IN HOT PURSUIT. IMAGINATION AND A SENSE OF HUMOR IS PART OF THE FUN OF COLLECTING.
