Lot 50491 – German States, Bavaria – 1849 1 kreuzer, two negative

German States, Bavaria – 1849 1 kreuzer, two negative glass clichés joined by Sperati to create a tête-bêche pair and additionally mounted on a bigger glass with traces of white tape applied from a previous process. Produced in a striking dark indigo-turquoise colour, this being a most unusual colour as Sperati preferred the red/vermilion or black shades, with each matrix marked “C. VI”. Coloured around the stamps to highlight the area of design and create contrast. Dated “12/49”. Unique in this remarkably unusual colour for Sperati clichés.
