Barbados: 1861-70 (1d.) blue, unused.
Printer: Perkins, Bacon & Co.
The first consignment of the 1/- stamp of the 1861-70 series, showing Britannia, were sent out to Barbados by the printers, Perkins, Bacon & Company of London in April, 1863.
The 50,000 stamps should have been printed in brown-black, but on arrival they were found to be printed in blue, the colour of the 1d stamp (an example of which is shown here), in error.
Almost all of the errors were returned to England, to be exchanged for new stock in the correct colour. A few examples were kept for a postage label album, and one of these is now in the Tapling Collection. Less than a dozen are known to exist today.
