I've talked about this more than a few times in the past, but I have to do yet another post about it. When Takuro Ishii first broke into NBP back in the late 1980's/early 1990's, he did so as a pitcher and went by his "real" name, Tadanori Ishii. The pitching thing didn't really work out that well for him and he converted to the infield in 1992, changing his name to Takuro at the same time.
As far as I know, there's only one contemporary card of him as "Tadanori Ishii" and it's from the 1990 Takara Whales set. I was lucky enough to track it down on eBay recently:
