Lot 61754 – 1860 60c pale brown, on underpaid and taxed cover to Argentina with Salto ornate oval hs

1860 60c pale brown, fine impression, a very fresh and large margined example, on 19.1.1860 entire letter to Buenos Aires, tied by bold strike of ornate “ADMINISTRACIÓN DE CORREOS/SALTO” oval hs, being underpaid for the single 120c rate to Argentina, charged in manuscript “1p” (peso) on arrival (also tying the franking) and collected for home-delivery mail and not related to the insufficiently franked rate, making this letter even more exceptional; a unique cover as a result of the three following characteristics: the oval cancellation -normally accompanying the « scarab » of Salto- was very rarely struck on stamps, the elusive manuscript due on receipt, as well as the very rare franking on mail sent abroad; a fascinating postal-history showpiece; cert. Hernández Rocha (2008) and Díaz Paulos (1981); ex Hoffmann and Scott.
