It is Chinese, apparently. There is one exactly like one of the butterflies on the site that begins with e and ends in y that is described as:”Chinese Porcelain Celadon Blue and Iron Red Silver Accents Box Signed” the pictures on that one could have come from mine! I found another that has the same mark on the bottom and it seems that it comes from the Qing dynasty, either Guanxu or Kuanghsu and I already knew it was the Nian period and zhi make. the difference in price is 10 fold, literally, so am aiming for the lower amount. All it took was your wisdom. I will do nothing until I hear from you, as I trust your opinion more than a salesperson’s. thanks again
