What told you was "I don't know anything about them. You should try Ryan Christof."
Have you tried Ryan? Here is his web site.
http://cubanbaseballcards.com/
You could also reach out to Al Jurgela. He is a member here and an expert on Negro League and Latin American cards too.
Seems to me that the more you resist taking recommendations for experts and the more you argue with people here over answers you dislike, the more it looks like nothing anyone tells you will change your mind about these cards, so it isn't a worthwhile endeavor to keep responding.
I'm out.
