Cuban cards are just about the only true playing days cards available of most Negro League players. I still think it's pretty wild that you can find many of these cards under $100. Most are single digit graded pops at SGC, and few exist above 1 / poor.
Claro Duany was a very good player, a 3-time batting champion across Cuban and Mexican professional leagues and a Negro League World Series champ.
I'm holding on to the a-listers from this set, but I will be running a little sale in my vintage Facebook group of some guys of this caliber. Nothing listed yet, so if you are potentially interested in adding some Negro Leaguers to your collection, drop a comment.
