I apologize in advance if putting up this link isn't proper. I have a little blog focused on the Dodgers and collecting, and I put up a post recently on a trade card set in my collection. It's the ACC #H804-6 Forbes Co. set.
I thought I'd note that the most recent Keetz guide on trade cards only indicates one variation; whereas, I have at least three different variations in my collection - red, black and no letters.
