I do have one more of these, of Rickey Henderson for stealing 130 bases in a season, which I posted earlier.
Other than the Henderson, which I bought recently, I don't know where I ever got these, but I do have a theory. I was reminded of this when Toys'R'Us went out of business recently. I think I used to buy repacks there. They would have a few baseball card items on a shelf, including, I'm sure, Classic sets, since Classic was a game, and their own branded boxed sets. I think they would have blister packs or something similar proclaiming 100 baseball cards for $3, or something like that (I'm just guessing about the price). That would be a possible place to pick up odds and ends like a handful of cards from a boxed set. Anyway, thanks for reading!
Postscript: In the first few months of this blog, I showcased all of the old boxed sets like this that I own. I've only bought one more of the kind, the 1985 Circle K Home Run Kings set. I decided to try to make a list of all the 80s boxed sets like this that I don't own. It's kind of depressing how many of them there are, not because I'd like to have them, but just because they're all so repetitive. Here's the list, as far as I can tell, of 80s Fleer and Topps boxed set that I do not own, through 1989 (it looks like 1988 was the peak of this genre, although they did keep making a few into the 90s).
