This is a scarce Argentine postal card letter (Tarjeta-Carta), denominated at 2 centavos, featuring the portrait of Domingo Faustino Sarmiento (1811–1888), a former President of Argentina and a key figure in the development of education in the country. The design is printed in blue with a diagonal patterned background and the inscription "Tarjeta-Carta" at the top. Unlike regular postal cards, these were issued in a format resembling a folded sheet with perforated edges, intended to be written on, folded, and sealed for mailing without an envelope.

Such stationery pieces are prized by collectors of Argentine postal history due to their distinctive design and limited postal use. The combination of portraiture, official coat of arms, and the experimental "letter-card" form makes this an appealing item for those specializing in South American classic issues.
