Hi All, I wonder if I could add one more example to the discussion please. It's an iridescent perfume bottle about 25cm high including stopper. It appears very similar to Ross' unknown #2 perfume (his photo #4) with the cross-over applied glass trails and general characteristics. I'm pretty sure mine is by Tina Cooper. I've attached a pic of the signature (for what it's worth with my photography) which is very similar to that on a piece of Tina's Sealife vases that I've got. The T almost looks like a Y. Also inscribed on the underside of the foot is the date 199? (perhaps 1999), a cursive L right in the middle of the pontil, and what I though might have been the name of the piece, which looked something like Matrix (and there's more after it, but indecipherable to me). I don't think it says Martini Glass, but I guess it could. So it's quite a busy base. Thanks, Andrew
