The 1897 series of overprints and surcharges includes some of the rarest stamps in British Empire philately. Another noteworthy issue is the Wilberforce set commemorating the centenary of the abolition of slavery in the British Empire and the death of William Wilberforce. The set of thirteen stamps went on sale on 2 October 1933 (Figs. 4 and 5).
