How I became a novice DPRK stamp collector

From 2000 to 2006 I visited North Korea 15 times, each time during 4 weeks. During those 4 weeks, I spent weekends and rainy days in the hotel (Mt. Myohyang or Chong Chon Hotel). Also, on my departure from the country, I spent 3 to 4 days in the capital Pyongyang (Yang Gak Do Hotel) waiting for the flight. While in the capital city, I spent time doing a tour of the Central Stamp Museum, the War Museum, and many other tourist attractions and sites.
