Recently a blue-and-white porcelain plate came into our attention. We believe that this plate is from the 9th century, or the late Tang dynasty imperial court, which makes it one of the earliest surviving pieces of blue-and-white porcelain ever produced. Measuring approximately 49 cm in diameter and 7.6 cm in height, it is also the largest Tang dynasty blue-and-white plate ever discovered. This plate belongs to a collector from San Francisco, California, who wishes to remain anonymous. We will report any follow-up story related to this rare piece. Stay tuned.
