Hello,
I purchased a cloisonne vase/bottle at a yard sale that has a mark and maybe signature on the bottom. It is 6" tall and very beautiful without any cracks or chips and holds water beautifully. The bottom has a red triangle with a possible number eleven within and a signature or symbol near the triangle.
I would appreciate any help identifying the cloisonne vase/bottle. It is not made of metal and believe it is pottery/clay/ceramic.
I am including pictures.
Thank you for any ideas for identification.
