 Small differences between the two include the roundness of the face and the lack of plumpness of the lotus petals of the base of the Asian Art Museum image along with the more skillfully carved flame patterns and shape of the mandorla.No inscription was carved on the back of the mandorla but the consensus of Japanese experts dates the image to a time in the 6th century earlier than that of the Yŏn'ga Buddha.The lack of inscription and the subtle differences in styles means that the statue has not been attributed to a specific state in the Three Kingdoms period.
