Stamp of the territory of the Papua New Guinea

From 1946 and prior to the issue of the first pictorial set in 1952, Australian stamps of that period were used as postage in teh teritory. Therefore all stamps from 1946 to 1952 bearing Papua and new guinea post mark should striktly be included in a collection of stamps of the country.Such stamps are of some interest to the specialist but,not being of a popular nature, it is doubtful whether any but the extremely high values would have any value to the general collector
