That photo was part of my collection from years ago, all sold (or chucked).
I think I remember seeing the 'dolphin' design on old canisters in Millers somewhere.
I believe the Hornsea cruets are in the 'Alpine' pattern, I sold them long ago ?6-8. I think I remember a complete set on the Antique's Roadshow priced at a whopping £100, eh? I also saw a Leonardo crown shaped teapot priced at £100, eek.
