Ceylon. Birds. Issued 5 February 1966. Four values (5c, 15c, 60c, 75c) were added to the definitive series introduced 1 October 1964. An imperforate miniature sheet (with simulated perforations) featuring the same four designs was released simultaneously.
The 60c Junglefowl exists with several striking varieties – including missing red (affecting the body feathers) and blue shift (affecting the plant and tail feathers). Find these and others here.
