Chontal Pre-Columbian Stone Figure

This ancient Pre-Columbian stone figure from Guerrero in Mexico is carved from an irregular stone with a face with deep seated eyes, wearing a headpiece with three lobe and standing with his arms crossed over his chest.  His head leans slightly to his left.  He has a very old tag on his back, much of which is illegible, which says "pre-Aztec" and "Guerrero Mexi".
