・This is a replica of an Aztec calendar (Sun Stone) purchased from the museum shop at the National Museum of Anthropology in Mexico City about 35 years ago. (It is unknown if they still sell it.) ・This design is often sold on coins, etc., but I don't think items of this size and weight are often found on the market. ・Please see the 5th photo for the size. The weight is approximately 5kg. ・There are some minor impact marks on the surface (see the 6th photo). ・Price negotiations are welcome.
