Thanks Jo, that's brilliant! I wondered when something like that would show up, since everything else in that era seems to have been copied from somewhere else. There are a couple of prominent original designs from about 1939, and I'm not sure all made it through to production.
The petals vase was made in a posy vase size (it's either 1.5 or 2" high - will have to check, no time now), but this one seems to be more flared.
All the best,
