This is marked only Royal Albert - Bone China - England, and I can't seem to track down the pattern shape, though I believe the shape is Shelley. Condition is excellent.
I've been through the entire alphabet of patterns on RoyalAlbertPatterns dot com, and can't find this flower at all. The site a great read with fantastic photos, so if you've never been there you should check it out if you love old china!
I had no idea there were SO MANY different Royal Albert patterns. And if you do find the name of this pattern, or already know it - please email me, thank you.
