The Kerry Glass label shown in Adam's second link has same "flame" logo as the IOW one, but the stamp on the base of the vase, as also shown in Adam's link, is a mirror image. That's interesting.
I had forgotten all about Kerry Glass after first seeing three paperweights decorating a window ledge in a Cornish bed & breakfast establishment around 1999. And then I was reminded about the company when I got a copy of Ivo's glass fact file a-z. Soon after, I forgot about them again as I have not (until now) seen any paperweights, or vases, by Kerry Glass.
There's no information about the company that I know of in the paperweight literature! Other than references for places to visit when in Kerry (Fossa), there seems to be no information articles on the Net, but I see that there are occasionally eBay listings for various pieces.
