Lot 50586 – Spain – 1851 2r Queen Isabella II, glass support cliché

Spain – 1851 2r Queen Isabella II, glass support cliché in black with handwritten production notations, together with a cliché on celluloid in vermilion with reversed image, and an essay on paper with notations on back alongside one of Sperati’s characteristic fingerprint colour trials. A spectacular and eloquent trio of separate working clichés, all produced from the single matrix.
