Nipper, the "HMV" dog

Nipper (1884–1895) was a dog that served as the model for a painting titled His Late Master's Voice. This image was the basis for the dog and trumpet logo used by several audio recording and associated brands: His Master's Voice, HMV, RCA, Victor Talking Machine Company, RCA Victor and JVC.
In 1898, three years after Nipper’s death, Francis painted a picture based on a photograph of Nipper listening intently to a wind-up Edison-Bell cylinder phonograph. In the painting, Francis substituted a disc gramophone for the phonograph shown in the earlier photograph.
The slogan “His Master’s Voice” along with the painting was sold to The Gramophone Company for 100 pounds sterling.
