A scarce colour variety and highly sought-after.
This is probably the most popularly collected area of stamps from Rhodesia, known affectionately as "the double heads", featuring Queen Mary and King George V. They are also widely considered in philatelic circles as being amongst the most attractive stamps ever issued in the world.
