This poster advertised an evening at London's Oxford Music Hall in May 1911 in honour of the music hall and variety performer G. H.Chirgwin (1854-1922), who was presented with a 'Testimonial' to fifty years in the business. Otherwise known as 'the white-eyed Kaffir', George Chirgwin started as a black-face minstrel but accidentally developed his trademark appearance of one eye painted white in a diamond shape. He would wear a very tall hat and long white coat over a tight-fitting dark jersey and tights. His act consisted of comic patter and much of it relied on Cockney humour and references. He also played various instruments, and sang songs, his favourite being 'My fiddle is a sweetheart'.

There was a crowded house for the Testimonial. Chirgwin began the evening performing some of his best-known songs, after which he appeared on stage surrounded by the committee who had awarded him the honour. The Testimonial - a large, framed illuminated address - was at the back of the stage and there were speeches, a presentation of a 'generous sum' which Chirgwin donated to the Variety Artistes' Benevolent Fund, and gifts of a specially-made instrument, a 'phono-fiddle', and a silver cigarette case.
