Totally agreed!
Back in the 1990s my wife and I went to a negro league baseball store in Tennessee that we found during a vacation there. I was hoping to pick up a set of cards highlighting all the players of that period. There wasn't a set to be had. Best they had was a poster with all the greatest players from that league highlighted (which I purchased).
I would love to see a set of not just the stars but all the players.
My son and I go to Cooperstown every year for the Hall of Fame inductions and I remember when he was young there were a couple negro league players who had tables set up to sell autographs. We'd always make a point to stop (they usually didn't have many people around their tables) and talk to them about their time playing ball. My son would find their stories captivating to listen to.
One of those same years when he was little, we were checking out the Jackie Robinson exhibit inside the hall and we were looking at the horrible letters Jackie received. Letters threatening his life and things like that and I remember saying to my son that if it wasn't for players like him, dealing with all that horrible stuff, we wouldn't have players like Rickey Henderson, Reggie Jackson, Ken Griffey Jr, etc. When we were discussing that, an older black man walked up and put a hand on my shoulder and said "thank you for teaching him about this."
Kids should have cards of these players to have those types of conversations about and to learn about the history.
