Korea. 1884–1990. Very interesting collection in large binder. Eg several “Yin-Yang” issues incl. diff. perforations and a few used copies etc. Further many 1895- and 1897-issues specialized in prints/perforations etc. Some 1899 and 1902 Overprints, high values, Falcons etc. Also fine collection South Korea with better issues, complete sets and a few covers etc. Please inspect!
