Lot 80067 – German States, Saxony – 1850 3pf, group of two beautiful glass support clichés

German States, Saxony – 1850 3pf, group of two beautiful support clichés, one on celluloid in red-vermilion with dating March 1945 and Sperati`s characteristic production notes written around the area of design, also a very fine glass cliché with an impression of the stamp in a luminous white-gray. Five cancellation trials include a gray celluloid with two Leipzig datestamps, and four papers with working proofs of mute circular bar cds, numeral 15, Leipzig datemarks, and oval Leipzig datemark, all with Sperati`s production annotations. An extremely fine assembly that demonstrates the importance of the correct cancellations and the attention that Sperati bestowed on every aspect of his reproductions; unique, very fine, and deserving of further study.
