1859 - 2gr blue (NA), 1st plate, BL4 (slightly touched at bottom) and single copy, with 2gr greenish-blue, 3rd plate, from 'TERRANOVA' to Palermo. Exceptional rarity both for the use of two different plates of the 2gr, and because this is the only known block of four of the 2gr 1st plate on cover. Signed Gaetano Russo, certs. A.Diena, Colla and Manzoni (Sassone 6a+8b - Euro -)
