Instructional Markings

Postal Instructional Markings are a very interesting study in Papua New Guinea. Till now very little literature has been published on the topic. Searches and researching are here particularly in demand. Impressions on domestic mail are very helpful when organizing postal markings that are unique to Papua and New Guinea.
