Can you post a photo of the vase and the bottom so I can help?
I need to search about 30 web sites so please be patient.
I am sorry. I can not seem to find the information. The sites I have checked list any and all ceramics and the markings of those sought by collecters. This could mean that it is too common and not of value to collectors. How did you come by the vase? It is pretty.
Not necessarily. I owned a ceramic business in the mid 70's and used common molds to create a variety of vases and figurines. I did put my symbol on them which made them unique, but the vase itself was common in design. That is what I mean by common. A valued piece would be the FIRST and original piece that the mold was made from. It will have a unique symbol.
Thank you. You might consider taking it to a local museum.
