Lot 80018 – Brazil – 1843 “Bull`s Eyes” a remarkable group of two glass clichés

1843 “Bull`s Eyes” a remarkable group of two glass clichés (one dated March 1843; 100 years after the issuing of the stamp), and two clichés on celluloid, of which one in attractive vermilion with colouring around the design, all with image reversal, also two fine cancellation trials on thin papers, circular Correio Geraldacorte and line pm Uictoria; a very fine group that displays Sperati`s integration of cancellation with stamp reproduction.
