Shelley trio - pattern 11526

This trio is in fabulous condition. I could find no other examples of this pattern online so it is a rare treasure. The cup shape is the gainsborough low foot which was used from the 1900s to 1965. It is a bit of a conundrum to me as the pattern 11526 dates to 1926 but the style of the decoration is much more art nouveau than art deco. Perhaps there was a designer with a love of nostalgia. I was particularly enchanted by the green decoration that divides the floral vignettes.
