Someone wants to sell me this vase. I have done some research online about the mark but I haven't find anything. Any help? Thank you everyone
Hi Williamh, the faces do not look like this on traditional Chinese, notice the lips, eyes and wrinkles are to defined for Chinese Antique Porcelain, this is fairly modern.
This is only a few decades old, despite its Qianlong mark.
I would recommend to abandon this mark based way of identification/dating of porcelain. If you visit the main site under "Marks" you will find the reason why it is almost useless for dating.
