Hi all, thanks for the debate. It is definitely intaglio, which according to my Glass Fact file by Ivo, is "a decoration cut below the glass surface." The one I illustrated has a bevelled clear glass edge which then leads into the white outer layer(kind of cased) and the pattern is cut through the white to show the clear below. It is in pristine, mint, fab condition (as is the tray) and if I decide to sell it on e-bay, it'll have a high reserve. If it's at a fair, well, who knows? I sold a black and white pop art small handkerchief vase for over £50 not long ago(transfer printed), and this white intaglio one is 8" high and 7" wide approx. The transfer printed ones, although pretty and quirky, and I have a lot and love them to bits,are by comparison to this white one quite inferior. I agree that Miller's price guides are to be taken with a large packet of salt, and these books ARE described as "guides" , however a unique and special item will always find its right level unless there's a total world wide depression, God forbid!! Anyway, if anyone goes to the Smethwick venue and is able to glean some interesting chance information, hopefully it will appear here! Byeee
