Lot 50069 – Italian States, Sardinia – 1861 3 lire, group of five items

Italian States, Sardinia – 1861 3 lire, group of five items including three glass support clichés, of which two in gray-ochre and vermilion, each numbered “8/21” for August 1921, the third being a negative master cliché with retouchs within the oval in centre and the external area around the margins of the stamp, the cliché in vermilion with very interesting note: “17°x5%x2’30” ” denoting 17°C temperature, 5% of a chemical substance and the exposure to sunlight during two minutes and 30 seconds (as the temperature was fresh for August, we can presume that he worked in the very early morning when the day was fresher and he needed the sun for the exposure), and numbered “124” in his list of clichés. As well as two exposure trials on photographic paper with annotations “double” & “+fort 2 choisis” (stronger, two chosen); a unique group and additionally being a stamp which was unknown in private collections, with only the reproduction of a matrix from the Musée de la Poste of Paris in Sperati II handbook.
