BPA (1976) Provenance: Ferrary, Hind Note: In 1863 the printers, Perkins, Bacon & Co., sent a supply of 50’000 to the island. On arrival it was discovered that they were printed in blue, the colour of the 1d, instead of black. A new supply was dispatched and the « blue » error was not put on sale. Before disposing of these stamps, a number were removed and defaced with a cross in ink which has subsequently been cleaned. It is believed that only nine such error exist
