This original drawing is in a selling exhibition of cartoons in my native North Yorkshire, although as I live 275 miles away I probably won't be going to see the show.
The exhibition, Three Centuries of Cartoon Art, is organised by the Chris Beetles Gallery of St James's, London, but will be held at Nunnington Hall, near York. A colour version of the cartoon was in Prospect magazine in 2008.
You can see the full exhibition online here.
