First how big is your Vase, Ceramic or Metal. This is a Asian Story Art, usually has a story with the Art. As for value, these are usually not worth much, so many have been Made of Export over the past few decades, with only Made in China to go on, it would be hard to find the Maker or Cir. Generally these go for around $5.00 to $10.00 if they sell. I have tried to sell several of these style vase and so many on Ebay that chances are slim that they sell unless you start really low.
