Andy BaranThe link below has some information about the set. Ryan can certainly add alot more detail if he wishes. No one is more knowledgeable about the issue than Ryan. I can tell you that the cards are exceedingly rare, at least as rare as the most difficult American issues (E107 Breisch Williams, Four Base Hits, Just So Tobacco, etc.) Very few of even the most advanced Cuban collectors own an example.
