1979 Topps BB For Sale

Let me know if you have any questions. I have a bunch of other SGC-graded cards from this set that are dups to my set that I will put on sale as time goes by, including an SGC 88 Ozzie Smith rookie. Contact me if there's something specific you're looking for or if you'd like to make an offer for the SGC 88 Ozzie Smith before it goes on auction.
