Dominican Republic – 1865 First Issue 1r, a sensational group 15 items with two negative matrices, both with accurate retouches in many small areas, which were used to create the impressive copper engraved printing plate presented in this lot, seven die proofs on pelure paper including his two first attempts numbered « 1 » & « 2 » with the former showing a note reading « excés pression » as the pressure was too strong for the impression which indeed is blurred, and five essays on medium wove paper with one being an experimented slightly and not uniformly coloured in green when trying to get the colour of the background. A lot of great significance as it demonstrates that, contrary to what was previously thought, Sperati also used typography and not only lithography for his reproductions of this country, with the key elements being the matrices which were used to produce the engraved printing plate, and this demonstrating the typographic method; unique and fascinating.
