Lot 50093 – Romania – 1871-72 10b, the sensational group of nine items

Romania – 1871-72 King Carol “With Beard” 10b, the sensational group of nine items including the master negative on celluloid with painted surround in red with the purpose of blocking the light entering through the sides in the following process to produce clichés, six glass support clichés in usual shades of red, orange and black, judged by Sperati as the best ones to create contrasts, with interesting notes of Sperati in two of them featuring date March 1941 and “1° dos léger, voile 2′ ” (light exposure from the back with filter during two minutes), and other dated July 1942 with “22° x 5% x 30” “, out of the norm demonstrating in this case that a light exposure of less than one minute (30 seconds in this case) speeded the process with a good result, worked well under a high temperature of 22°C (the 5% refers to a chemical substance used in the process). An unparalleled group including the eloquently important master negative which was the key to initiate the process of reproduction; no matrices or clichés were known to the B.P.A. or the Postal Museum in Paris, and nothing but finished reproductions are found in the “Ultimate” collection.
