“There was a time when almost everyone in the country collected stamps. That was only about 20 years ago. For children at that time, stamps were like money, with which they could get beads or trading cards. Middle school and high school students learned about the world’s geography by collecting stamps, while adults considered it a ‘classy’ hobby. But times have changed. These days, doing what everyone else does is considered boring and simply a waste of time. That’s why the ranks of ‘yeopgi’ (crazy) collectors are increasing now. These collectors acquire virtually anything, and don’t care what other people think about their collections. The item may be trash to other people, but is a treasure to the collector himself.”
