This plate is absolutely magnificent and in mint condition. You probably will never find one like it again.
On the back of it (officially translated):
"National Palace Museum of Taiwan Replica of Original Made in the Year of Qianlong Emperor".
Qianlong (1735-1796) was one of the most famous and longest reigning emperors of China. The National Palace Museum houses some of the most valuable treasures that were taken by the KMT out of China after Chiang Kai-Shek lost the civil war to Mao and the Chinese Communist Party. These treasures are from Imperial China.
The detailed workmanship on this plate is truly remarkable.
Again, you will not likely find another, especially in such perfect condition.
