|Card front (black bank)|
This set's 50 subjects (checklist at CubanBall.com) played during Cuba's pre-revolution era, when foreign money and gangsterism held influence throughout Havana. (Indeed, Castro spoke out against this back-scratching corruption, making headlines as early as 1947 itself.) Amidst the country's political and social heat, American baseball scouts found Cuban racial integration favorable to tryouts and signings in the wake of Jackie Robinson's debut, as stateside teams added more non-white players. While helpful in a business-of-sports sense, some critics continue to find MLB's actions in Central America more exploitative of the area's poverty--pushing native sons to "escape" with a baseball contract--than supportive of local teams and fans.
UPDATE: Forgot to mention S.I. September 27 story about Cuba's announcement that athletes can sign pro contracts without defecting, a sea change in country policy that abolished paid leagues following Castro's rise to power. Not clear how (or if) this will change MLB approach to player scouting; it might just become more visible.
Owners of this gatefold album could stick all 50 players to a pair of 2x6 grids, with manager spots reserved for #1 Miguel Gonzalez above Deportivos and #2 Adolfo "Dolf" Luque (1920s MLB star) above Campo Alegre. I assume albums prove even more elusive than individual cards and appear only at auction.
Value: Haven't found a type card myself, so assume that set rarity also means prices fluctuate. 5-decade vet Minnie Minoso (#33) and Negro League star Martin Dihigo (#48) would command premiums from modern collectors.
Fakes / reprints: Haven't seen any in the marketplace, but they're possible. If you're unsure of Central American set authenticity, try an expert source like the Net54 postwar baseball forum and include scans when possible.
