Hi Gabrille,

Thank you for contacting Mearto with your appraisal inquiry.
I have handled Pre-Columbian objects for 20+ years and this is unlike any iconography used throughout Latin, Central and South America. I'm highly suspicious of this being Pre-Columbian as it looks quite a lot like a Martian in a UFO, which were popular in the 1950s and 60s and would acquire an antique patina if it had been buried (accidentally or on purpose) for a few decades.
