John - am I seeing your linked piece, and Christine's, as slightly concave 'ovals', and the piece here as having slightly convex ovals - or is it my eyes again? Perhaps the op will clarify on this vase. I suggested B.S. originally, which this is almost certainly not, because righty or wrongly I had assumed the pattern was convex as with 'large olives'.
Somehow I'm not seeing a match in the appearance of the optic patterns with the vase here.
I've seen the Christine's bowl pattern in the past, but no idea now if I ever knew the maker.
