Before South Africa was unified in 1910 the colony of Cape of Good Hope issued its own stamps, including the famous triangular philatelic examples that depict an allegorical figure of Hope. Initially produced by the security printers Perkins, Bacon in London, this example of the 1855-63 one shilling bright yellow-green is a particularly attractive example. Although it is not a rarity, it is representative of the outstanding stamps that can be seen at the British Library.
