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 clear photo of the marks on the bottom.
I also need one of the pattern used in your piece.
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 file" or "add file" link on your reply page or the "paper clip" found in the toolbar you see on your reply page.
