During the 1970s & 80s so New Zealand stamps reflected a very stylized, almost cartoon art design. The 1978 Agriculture / Lincoln College and 1981 Government Life Insurance Lighthouses are classic examples of this. A similar design form was used for the 1972 Ross Dependency Pictorial/Definitives.
This issue replaced the 1967 Ross Dependency Decimal Pictorials as the new definitive set and remained in circulation until the 1982 Ross Dependency 25th Anniversary of Scott Base stamps were issued. Although not a commemorative issue, the stamps were issued on the 60th Anniversary of Scott's Polar Party reaching the South Pole on January 18th, 1912.
