This is a Heinrich (H & Co.) Christine Line, “Arcadia” pattern 13-1/4″ oval serving platter. According to its backstamp it was produced in the Selb region, Bavaria, Germany, from 1930 until 1939.
This platter is in very good, used condition. It has no chips or cracks. It does have a few utensil / knife marks, which I took a picture of. It is still very pretty. Make sure to check the pictures before you agree to purchase.
