There are times when old imagery is irresistible to a cartoonist. Yesterday  was one of those occasions as Alastair Campbell, Tony Blair’s former Press Secretary, gave evidence to the Chilcot Inquiry on the intelligence published before the invasion of Iraq. Francis Barraud’s original picture of  Nipper the dog and the cylinder phonograph has inspired a lot of satire over the years. The version of the image most of us parody features a disk gramophone because that was what was being marketed and sold at the time. Barraud’s image is properly iconic, in that it became part of many peoples everyday life through its association with the recording firm HMV.
