This is an extraordinarily rare and unique carved bone Mayan plaque. This masterpiece is the finest I have ever seen and very few exist. It is 4 1/2" X 2 1/2" X 1/8". It is from the Aapo Bolon Estate which was collected by the family while living in Guatemala from 1920-1980. I inspected the entire collection of over 1000 pieces and found nothing incorrect in any item. This was the finest piece in the offering. It is from the Post Classic Period as it is made from Bovine bone. It shows nice age cracking and polishing. The back is textured as if it was buried against a textile or ceramic or other artifact attesting to its authenticity. The iconography is nothing short of spectacular and stunning. It screams pre-Columbian. I cannot find another Mayan carving in any media that even comes close to this depiction .The patina is beautiful. There is no way to over exaggerate the perfection and IMPORTANCE of this piece. It is simple amazing. It is a priceless piece of Mayan art.
