This is an extremely rare jade picture-plaque that dates to the Late Classic Period around 700 AD. In my 40 years of collecting, I have never seen one for sale. These plaques all belong to one school of carving known as Nebaj-type plaques because the first specimens to be found in situ in the Mayan area come from Cache 14, Mound 2, at Nebaj, Guatemala. All are made of special varieties of jades of Class 3. This type of jade tends to decompose, as in this specimen, which lends to its authenticity. It is 3 1/2" long by 2 3/4" wide. It was found by Frank Ackenback in 1978 in South Texas along the Rio Grande River and he has been the only owner. It comes with a Bill Jackson COA. Due to a recent diagnosed major health problem, I have dropped the price of this piece and all my items by at least 50% to at or below the price I paid many years ago. Now is the time to pick up a great deal. My loss is your gain. This piece was $12,000.
