WONDERFUL spray yellow roses pattern on this tea cup set by Delphine, Made in England.  Delphine Bone China was manufactured by Middleton & Co from 1889-1941.  This backstamp appears to be from 1930 to 1941.  The tea cup measures 2 1/2" tall by 3" across, saucer measure 5 1/2" across.  The cup handle is not smooth but has a rope-like feel with the raised areas painted in gilt.  A DELIGHTFULLY cheerful rose set!
