Maritime Mail of Spanish Colonies in America

Bolivia Outgoing Mail 1800 circa. Cover (flaps lacking at top and base) from Plata (then belonging to the Virreinato del Perú) via Buenos Aires to Madrid, struck on dispatch by red Italic "Plata." & "Perú." handstamps, taxed on arrival with "10Rs" marking within oval. A rare colonial mail from Bolivia, highly desirable as the only transatlantic mail known with the "Peru" postmark of Plata.
