Let's backtrack a bit. Before hunting for cards in Taipei, I traveled down the west coast of Taiwan visiting amusement parks and tourist destinations and taking in a couple baseball games.
I was heading back to the train station in Taichung after a day of sightseeing when I randomly came across a small baseball card shop. Actually, it was part card shop and part toy shop, and the toys are what really caught my eye at first. As soon as I saw the cards I started looking carefully.
Here are the cards:
I saw a small box of singles of these later when I was in Taiwan and at the time I didn't realize that different colors were parallels of the SPs. I think there was a black border parallel as well, or at least one other color. I didn't see any other "insert" sets in the box, so either there are no other special cards or they were sold already.
The Taichung card store was a short walk from Taichung Station. Leaving the main exit for the station, turn left and walk down the main street for a while, on the side of the street opposite the tracks. I don't recall how far it was nor anything specific about the look of the shop, but keep your eye out at street level for a store with toys, action figures, comics, or anything else of that nature in the window. The cards were located on the right side of the shop looking in the front door.
