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.
