This is a hammered sheet silver breastplate with the neatest iconography that I have seen. This piece screams pre-Columbian. It depicts a fanged anthropomorphic transformational diety war god figure in full regalia holding 3 double-headed snakes/serpents wearing an elaborate feline/monster headdress showing fierce demon facial features. It shows many levels of patination. It is 7.2" X 5.7". It is attributed to the Chavin culture. Similar figures at The Old Temple from the ceremonial center of Chavin de Huantar date this piece to 900BC. From a private German collection that was purchased from a 34 year old Peruvian collection of a museum curator. It is beyond rare. Museum quality.
