Nice find, Max! There's one point about the Hellenic pattern (two varieties BTW): you don't see it very often. Not many people have woken up to this fact and you'll rarely see examples on eBay, but Tony Cartwright did tell me recently it was not a very popular pattern, so it wouldn't have lasted long.
The other variety effectively reversed the vine and grapes pattern to the outer rim and used just two(?) silhouetted Greek figures in the centre. Personally I prefer the green version myself.
I have a suspicion there's also a blue version of this style, but I only remember seeing this when I wasn't really looking for Chance glass particularly, so it might have been me dreaming :roll: :wink:
