This is a beautiful Heinrich (H & Co) Christine Line, “Arcadia” pattern flat cup and saucer set. According to the backstamp, this pattern was produced in the Selb region, Bavaria, Germany from 1930 until 1939.
I have seven (7) of these cup and saucer sets, each one is for sale separately. They are all in excellent, used condition. I also have one extra saucer, which I will include for the first person to purchase one or more sets.
