I expect that this vase is probably too old to ID but am ever hopeful :-)
It is dark kingfisher blue in colour with pontil as in image 4. The vase is hand painted all around to depict a koi carp pond it has lily's, white, cloud like koi carp and a central strange animal with a snake like body. All of the lily's have a gold outline (like cloisonne effect). Any help appreciated as always or advice where best to look to ID.
