It is interesting to study geography through postal history. Recently I acquired this postcard. I noticed it because the sender’s address was written as “KyongSong”, the old name of Seoul during the Japanese colonial era. So at the first glance it seems this was a card sent from the South to the North.
Later I took a closer look at the postcard. This card was a 50ch postcard from North Korea, sent to Pyongyang, on July 1, 1950, just 3 days after “Seoul liberation” (the term used by North Koreans to describe when the North Korean troops entered Seoul on Jun 28, 1950). The postmark shows that this card was sent from YangYang, KangWon Do, and the postmark is of the North Korean style.
