thanks for the link - interesting, but unfortunate that unlike some signatures, these appear not to help with dating, and seems owner of the site doesn't include any vases. I'm not in any way doubting that my vase is original, and the appearance of the signature does look to agree with others, so I'm happy with this one being bona fide. I can't imagine that date wise mine is anything other than post 1950 - of course I would have loved a large bulbous cameo etched vase showing orange Monbretias, and worth about five grand. Mine is a tad boring, but suppose if you wanted an overweight, clear vase, then this would suit.
I was out on my walk when this came into view, so had to shove it in the rucksack - fortunately didn't have too much more walking to do.
thanks again.
