As I had questioned before in the chipboard, the 2 Habana Casino dice of different colors WERE NOT FROM CUBA. After 3-4 years of research in Cuba and in the USA about the HIstory of Cuban gambling for a catalog hopefully soon to be published, I have not found anywhere any indication of a casino of such name. I called the person in Cuba who has by far the largest Cuban casino memorabilia collection and perhaps the most knowledge (cannot say the name as he still lives inCuba), and he confirmed the fact that it would be almost impossible that such a casino would exist in HAVANA. The casinos from Havana are well documented, including the ones from the red district. I called the other 4 people I know have the most knowledge, in USA & Cuba, and the same answer, Such a casino with such a name would not have gone unnoticed. The casinos in Havana , once you organize places and time are not much of a maze.
During my 3+ years of reseach , in History books here and in Cuba (..sorry I forgot I could not go there), nothing. I decided to go the other rout. Outside of Cuba. One of the largest online betting houses and sport books is called "Habana Casino". I did find the history of an old Estonian casino, also by the same name and John Genualdi who was also helping me figure out the precedence of these dices, found the existance of another Havana Casino in Rusia. But that is it!!!
The color of the dices are of no important. specially from outside the USA, where they come in all colors.
But, bottom line, it is extremely unlikely, not to say almost impossible that these dices came from Havana, CUBA. Hope those are bidding for it know what they are doing. If I thought there was any possibility that these were from Cuba, I would be bidding over $275 minimum for each pair!!
