There are seven cards for each team with the exceptions of the Doosan Bears and the Lotte Giants who each have eight cards. I don't pretend to know enough about Korean baseball to state with any authority at all over whether or not this is a good representation of the best players in Korea or not or if there are any significant players left out. Off hand, I recognize a couple name - Lee Dae-Ho of Lotte who is now with the Orix Buffaloes and Ryu Hyun-Jin of Hanwha who has asked to be posted to the US. There are a couple Western players included in the set - Jose Capellan (Hanwha), Edgar Gonzalez (LG), Karim Garcia (Lotte) and Doug Clark (Nexen). Oddly enough, each of the Western players is only identified by his last name except for Karim Garcia.
Here's some example cards:
Another odd item about the cards is that the front of them have "rock-paper-scissors" symbols like old Japanese menko. I asked Ralph Pearce if he knew if there was a tradition of menko in Korea. He said yes and pointed out that he actually has a Korean menko (actually called "takji" in Korea) baseball card set from 1983. However, those cards don't have the "rock-paper-scissors" symbols on them. He did say that there was a tradition of "rock-paper-scissors" in Korea so maybe that's why they included them on the cards.
According to Thomas St. John, the guy I bought the set from, the cards were sold in clear packs of eight cards each. Jason pointed me to an entry on a Korean blog that talks about baseball cards (among other things) that showed a display rack of these cards. Unfortunately for me, the entry was written in Korean (naturally) and for whatever reason has resisted being translated by Google translate or BabelFish. I did try copy-and-pasting the text at the bottom of the post into Google translate. I think it says something about the blogger finding these cards in a stationary store and regretting not buying more of them. He also has no idea who made them and suspects that they are unlicensed.
One of the other entries on the Korean blog talks about a baseball card set from 1998 that I was previously unaware of. I've been learning lately that there are actually a lot more Korean cards than I had known. I've picked up a bunch of 1994 Teleca cards from Robert Shadlow (another of the Japanese baseball card pioneers) and I intend to do a post about them in the near future. Thomas St. John also let me know that he's preparing a book on Korean cards that he hopes to publish next year - it sounds like it will be a comprehensive list of all known Korean baseball cards.
