Maritime Mail of Spanish Colonies in America

Argentina Outgoing Mail 1810 circa. Cover front from Capilla del Rosario to Naval (Spain), most probably carried via Cádiz, bearing two-line "Capilla De/Rosario" and straight-line "Franca" handstamps, both in red, the latter being unlisted by Tizón-Guinovart. Extremely rare postmarks from a small locality, further enhanced by being applied on transatlantic mail.
