The set has appeal as a Sports Topical, particularly to Latin American collectors who specialize in stamps honoring this regional competition.
I believe it inevitable that Cuba will join the fold of more-or-less free nations, and that tourism and trade will explode as a result. Currently, the average wage of each of the 11 1/2 million people living in this "socialist utopia" is under $20 per month, and GDP per capita is 107th in the world. Annual GDP growth has been high, averaging 6.4% over the last 5 years, but given the levels of corruption and favoritism shown to high ranking Communist Party members, it's an open question whether much of that new wealth has been filtering downward. Eventually, something will have to give. The current market for Cuban stamps, especially of the Pre-Castro Period, is bolstered by interest of stamp collectors within Cuban-American community, currently about 1.6 million strong, and far wealthier than their compatriots on the island. Interest in Cuban stamps is likely to increase, especially given the likely prospect of a replacement of the stale, "gerontocratic" regime within a decade or so.
"The Stamp Specialist" blog features my buy prices for stamps which I am interested in purchasing. I've posted a buy list for Cuba. Viewing dealers' buy lists every now and then is an excellent way to keep up with the vagaries of the stamp market.
