What is the height of these? At your convenience, please send a clear in-focus close-up of the design on this and of the marks.
Thank you for the dimension and view of the mark - do you have a photo of the design on the vase that you can send here.
Thank you for the images. Please allow me some time to look these over and to write your assessment. I will post it here when complete.
If authentic, the pair would carry an auction estimate of $6000 - $8000 with a potential of reaching $10,000. However, the mark could possibly be associated with the Sevres-Style factories of Feuillet, which still garner substantial sale values. I encourage you to contact the porcelain departments of both Christies and Sothebys. It is free to contact them and they can also provide a possible estimate too.
Just checking in to see if you viewed your answer and if you are seeking further assistance?
Please let me know.
