I will be sharing US issued sets that have Korean players in them when referencing the country or WBC. This set has 10 total cards, 3 of which are Korean players. Chan-Ho Park (박찬호), Byung-Hyun Kim (김병현), and Sun-Woo Kim (김선우). The set also includes three Japanese, one Netherlands, one Australian, one Canadian and one Cuban.
I like the design of this set. I like how the country flag is in the corner of the card and the "League of Nations" has a raised font which is cool. What's ultra cool is that Leaf actually included both languages for the bio on the back of the card. I can't say I have ever seen that.
