These four cards probably aren't worth all that much, but they are of players that helped define Japanese baseball in the late-80's and much of the 90's. Or at least, that's how I think of them.
Sorry the quality isn't all that great. I took these with a camera because I was too lazy to dig out the drivers for my scanner. I'll replace these with cleaner images when I get around to it. I also have a few others from the same year (1991) that I think are equally interesting -- I'll post them when I have some more free time.
