Lot 50123 – United States, Confederate States – 1863 10c, assembly comprising 20 items

United States – Confederate States – 1863 10c, assembly comprising 20 items including one retouched master negative on film and mounted on glass, with affixed note “pas terib.” (‘pas terrible’, not terrible), seven glass support clichés (of which five reversed) in indigo, orange-vermilion, black, gray, ochre and red-brown, dated July-August-37, March-Aug.-41 and March-55 (after Sperati’s sale to the B.P.A.), including interesting annotations with “vert” as the green colour of the filter used to obtain the orange-red after an exposure to light of “3’30” ” (3 minutes 30 seconds) and 5% of the chemical substance used, “soleil sombre” (sun-shadow); two clichés on celluloid, one dated “2/51”, the other with “clé. usé” denoting that it was a previously used and recycled, as well as one finished signed reproduction; cancellations: six glass support clichés and three essays on paper with dates “12/44” & “4/53” and examples of Mariet, Nashville, and “New York/Paid”, this being erroneously used by Sperati as it was applied on transatlantic mail. A unique and spectacular group; of great significance as no examples of clichés or matrices recorded in the Postal Museum in Paris and the “Ultimate” collection.
