Blackface is the practice of non-black performers using burnt cork or theatrical makeup to portray a caricature of black people on stage or in entertainment.
This reproduction of a 1900 William H. West minstrel show poster, originally published by the Strobridge Lithographing Company, shows the transformation from a person of European descent to a caricature of a dark-skinned person of African descent.

The Dreadnought hoax was a practical joke pulled by Horace de Vere Cole in 1910. Cole tricked the Royal Navy into showing their flagship, the battleship HMS Dreadnought, to a fake delegation of Abyssinian royals. The hoax drew attention in Britain to the emergence of the Bloomsbury Group, among whom some of Cole's collaborators numbered. The hoax was a repeat of a similar impersonation that Cole and Adrian Stephen had organised while they were students at Cambridge University in 1905.
