1950's Harlequin Cup and Saucers - Edwardian Bone China

I also bought these trios of Cups, Saucers and Plates. I think they are probably from the 1950's, and I like the bright cheerful colours. They are a bit of a mixed lot, as the green cup is a different shape than the others, and the black cup has a saucer from a different maker. All except the black saucer are marked Edwardian Bone China, 22 kt gold.
