Lot 80057 – German States, Bavaria – 1849 1kr, a beautiful glass support cliché with tête-bêche

1849 1kr, a beautiful glass support cliché with a very sharp impression in light-grey of the tête-bêche, in type C of the three types that Sperati produced, an extremely attractive and tidy cliché that displays beautifully; Sperati produced tête-bêche pairs and strips, that were complete fabrications and had forged cancellations, a cliché on glass of the highest rarity, with nothing similar preserved in the “Ultimate” collection or the Musée de la Poste of Paris.
