Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
Please send me a photo of the marks. I also need a photo of the vase.
You may need to use the macro function (flower icon) of your camera to get a good clear photo of the marks.
If you cannot get a good photo, then sketch the marks and take a photo of the sketch.
To send photos you may use the "reply to expert" or "add files" in the blue box link on your reply page or the "paper clip" found in the toolbar you see on your reply page.Please do not send in ZIP format. The jpg or jpeg format works best.
An explanation of this method can be found here:
Please tell me how tall the vase is.
There is absolutely no hurry at this end.
