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 four photos ......
two of the tea cups
the two marks on the bottoms on the same tea cups.
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 "attach" or "add" link or "paper clip" you see on your reply page.
