This seems to be quite a rare variation of the "Spring" pattern by Glyn Colledge at Denby c 1954. I had a small lidded dish with this variation quite while ago - but broke it sadly before I got to photograph it.
This variation of "Spring"has lovely cornflower blue flowers, and a similarly coloured rim (the piece I dropped had a cornflower blue lid instead of the usual grey for this design)
These are 4 quite large serving dishes or ramekins, that fit together to make this classic midcentury centerpiece.
Below is the usual "Spring" design where you can pick out the slight difference in the rim colour, and also notice that the leaves have slightly different colours and patterns, and the bud hasn't quite burst into bloom yet.
