A very left field suggestion - Aseda similar to this Decanter by them.

I have found a few other examples of pieces that have a similar design. Fenton piece is the same color and pattern, less the opalescent and skill. There were some owls with the same tooling on the body. And I found the artist/vase you shared. I just know I was not on the right track when I came here. I still love the vase and it now is displayed in my kitchen. Next to the another (I am assuming Chinese vase), a stunning Houze vase, a reproduction jadeite hand, a Smith compote, Avon bottle shaped like a rino, a vintage Fiesta gravy boat, chipped McCoy vase and a Northwood bowl. I am working on having a rainbow in my kitchen lol. Mainly anything to hide that wallpaper that I am not looking forward to taking down. It Is all crammed together right now because I am trying to thin out some pieces and need to see what colors I am lacking and what colors I need more of. So as you can see, I am not about the brand, I am just a collector of all things I find pretty or ridiculous (since the rhinoceros) be it pottery, glass or copper. (Edited to correct the autocorrect of Houze)
