Early years of North Korea, a gold mine for the specialist
Little is known about the early years of philatelic North Korea. And it is certainly not a popular collecting area in the Netherlands. It was also quite difficult to obtain stamps from that country. And they didn't look very good either, many must have thought. North Korea came into existence on August 15, 1945, after having been occupied by Japan since 1910. After the atomic bombs, Korea was divided into two occupied territories: the south by the United States and the north by the Soviet Union. Under the influence of the Soviet Union, the Communist Party came to power on August 29, 1946.
In North Korea From March 12, 1946, stamps were issued featuring a flower (the Rose of Charon) and the Diamond MountainsOn April 22, 1947, a stamp was issued featuring an image of working women in the countryside. The image is barely recognizable. The stamp was printed on three different types of paper: white, brownish, and even brown wood-containing paper. The colors also varied from light blue to dark blue, some partially perforated but most unperforated.
On September 8, 1948, in Pyongyang The Democratic People's Republic of Korea was proclaimed. This resulted in the issuance of new stamps. On February 9, 1949, a stamp dedicated to the General Elections was released. The stamp, with a face value of 6 Won, featured the country's flag. Here, too, various paper types and color variations can be found. Part of the print run was provided with a type of perforation in the form of small straight cuts, allowing the stamps to be torn from the sheet. The green 1 Won stamp depicting a Korean award, the Order of Merit, was issued on April 4, 1950, still on different types of paper and in color variations.
On June 20, 1950, the fifth anniversary of the country's liberation from Japanese rule was celebrated. The series of stamps consisted of two 1 Won stamps, one 2 Won, one 6 Won, and one 10 Won. Here, too, there were many color variations and paper types. It is clear that the stamp printing presses in North Korea did not deliver optimal quality. The many types of paper used, along with the poor printing technique and finishing, did not produce 'beautiful' stamps.
But for a specialist, these stamps are ideal for discovering all possible variations. This requires extensive knowledge and patience. Knowledge of printing techniques, printing inks, paper types, perforations, and so on.
However, if you have access to a large number of these stamps, describing them accurately is a challenge—a true gold mine for the specialist. Could you muster the patience?

Were you able to get your hands on a large amount of material perhaps???
Indeed, for the traditional philatelist who yearns for primitive printing techniques like lithography or letterpress, such a Korean stamp is naturally ideal. But thanks to its primitiveness, it is also suitable for any small basement or garage printing workshop, with all the disadvantages for the “serious philatelist”….
