This attractive 1999 joint issue between China and the Democratic People’s Republic of Korea highlights two celebrated East Asian mountain landscapes, symbolizing friendship and shared natural heritage. The first stamp depicts Mount Lushan in China, shown with mist-covered peaks and a traditional pavilion, reflecting classical Chinese landscape painting aesthetics. The second stamp features Mount Kumgang (Geumgangsan) in Korea, famous for its dramatic rocky ridges and cascading waterfalls. Printed in harmonious soft tones, the pair forms a visually balanced commemorative set sought after by collectors specializing in joint issues, Asian scenic themes, and late-20th-century Chinese commemoratives.
