Lot 50061 – India, 1856 unissued 2a, Group of 6 items

India – 1856 unissued 2a, two negatives that served as Sperati’s master matrix for making the printing cliché, of which one with a better impression and handpainted surround in red which must have been the chosen one by the artist, two glass clichés in the frequent colours used by Sperati to obtain better contrasts: black and orange-vermilion (red or vermilion shades), the latter with notes indicating the 5% & 8% applied of two chemicals and the « 2′  » two minutes of exposure to light, and two clichés on celluloid green-lemon and olive-black, this produced with 22°c, 6% of a chemical substance and 3 minutes of light exposure; in the « Ultimate » collection a perforated reproduction was offered as unique. Absolutely unique and a major rarity of India, with nothing similar recorded in other collections or archives, with the connotation of the two master clichés making this lot even more desirable and exceptional.
