Mt. Myohyang Hotel, summer of 2003. I was doing my morning walk around the hotel lobby and saw the telephone booth lady putting out a display tray of stamps in the display cabinet. After she had finished displaying, she started to cut sheet stamps to individual stamps to replenish the display trays. This is when I noticed two different stamps in a single sheet. I was very curious about what I had seen and asked the lady why these stamps come in a single sheet?
Her reply was that to minimize the inventory at the local shop, the central stamp printing office printed this way. She also said that there are different versions of sheets with the same stamp and showed me 5X5, a total of 25, of the same stamps in a single sheet. Because this sheet of stamps being unique, I purchased that sheet on the spot. Later, I found out that this telephone booth lady was in charge of all telephone booths in town and ranks high in communist society. Because of her status and job, she was able to make frequent trips to Pyongyang and the central stamp warehouse. Most of my sheet collections were purchased through this lady.
