Gronchi Rosa

The Gronchi Rosa is a rare Italian postage stamp design error showing outdated country boundaries between Peru and Ecuador. It was one of the stamps of a 1961 issue for the voyage of president Giovanni Gronchi to three South American countries. Issued on 3 April 1961 but withdrawn the same day after the error was observed. The withdrawn stamp was replaced with a grey version. The 205 liras rosa was intended for the stopover in Peru. The artist made a mistake with the boundaries between Peru and Ecuador. The rose-colored stamp was quickly replaced by a grey version with corrected boundaries, but some philatelic souvenirs using the Gronchi Rosa already existed. A forgery of this stamp is known to exist. Legal validity was due to begin on 6 April 1961, the date of the President's departure, but validity was suspended and the stamp was replaced with the "Gronchi grigio".
