DELICATE detail roses decoration on a lovely tea cup and saucer by Hammersley & Co. - with a rounded square tea cup rim.  The backstamp reads Bone China, Hammersley & Co, Made in England.  The dating of the backstamp appears to be from 1887 to 1932.  The set does not appear to be numbered but has the initial M with numbers 123 in red.  The tea cup measures 3" tall by 4" across.  The saucer measures 6" across.  A WONDERFUL vintage set!
