A typical Olmec fat-cheeked visage. The stone, however, has an unusual patina, probably caused by ceremonial burning. Also, the top edge seems to have been broken in ancient times and redecorated with transverse grooves. There are bi-conical drill holes at the upper lateral corners for attachment. Also the eye and mouth corners and the nostrils have drilled pits. The parted mouth reveals a toothless upper gum. The back of this mask is trough- shaped, and the whole is polished.
