3 Pesos 'D' Foreign Exchange Certificate-Narrow 'D'

Cuba's Foreign Exchange Certificate program ran parallel to the regular peso, allowing the state to capture hard currency from tourists and foreign workers without permitting dollar circulation. These "INTUR" series notes — named for the tourism institute that administered them — were pegged at parity with the US dollar, which made them useful fictions: a Cuban couldn't freely exchange them, but a foreigner could spend them at designated shops stocked with goods unavailable in the ordinary economy.

The "Narrow D" designation distinguishes this variety from an earlier, broader typeface used in the same series — a minor but catalogued typographic difference attributable to plate revision at the Státní Tiskárna Cenin facility in Prague, which produced Cuban currency through much of the socialist period.
