Lot 60316 – Gold Coast – 1889 20s, an extraordinary group of seven

1889 20s Sperati forgeries, an extraordinary group of seven items including four stamps of the 1889 issue with their design chemically removed and affixed to thin plastic to just retain the ink showing the genuine cancellation (the unique item kept by Sperati for his reproductions), with an accompanying essay on paper of the “554”, “556” and “B 27” barred ovals, as well as a grey glass cliché of the “554” obliterator; also a negative glass cliché of the Winnebah cds. A unique group.
