This story has to do with 1975, but I'll mention it anyway.
It was September and I was very close to completing my 1975 Topps set. It was my first year of trying to complete a set. I had spend many allowances at the nearby Circle K on baseball cards and Wacky Packages stickers. For some reason, Lou Brock was really hard to get. Early one Saturday morning I went across the street to Jimmy's house. In the window screen I saw two Lou Brock cards. Jimmy was a real wheeler-dealer, and itt cost me a lot of football cards to get one of those Lou Brocks. I didn't care -- it was only football. :)
I still have that card. I've since upgraded, but I'll always remember how hard it was to get my '75 Lou Brock.
