Condition: It is said to have been bent at one time and thought to have been straightened (as it is currently) in the 1880s. The plate shows some oxidisation and ink remainders (likely from later reprints). Notable marks made (whether intentionally or by accident) since its use in 1847 include the following: – 1d: Small dot in the lower right corner ornament (probably from 1912) – 2d: Vertical scratch through “POST OFFICE” (occurred before the first reprints) – 2d: Horizontal score in the lower right corner ornament from 1912 PROVENANCE: 1847 Colonial Government of Mauritius – Mauritius Postmaster General Between 1874 and 1882 Dominic Henry Colnaghi (according to his own statement to the Commission of enquiry set up in 1914 by the Colonial Office on request of the government of Mauritius, he got it as a gift from an aunt). 1912 Nevile Stocken (bought it in London from Colnaghi for a “consideration in cash” 1912 David Field (unknown price) 1912 Sydney Loder (unknown price) 1930 (?)

N. & M. Williams numbering system), were undoubtedly printed with the plate. The tests also helped to corroborate that the plate was marked after its original use.
