Below caption title: Vox populi, - "We'll have a Mug! - a Mug! - a Mug! - Mayor of Garret.
Print shows Fox addressing a proletarian mob from some point apparently under the portico of St. Paul's, Covent Garden. He stands behind a railing, clasping to his breast the 'Pewter-Pot Bill', saying, "Ever guardian of your most sacred rights, I have opposed the Pewter-Pot-Bill!!!" The crowd look up at him, cheering and shouting "a Mug, a Mug". They wear blue and buff favours. In the foreground are half-length figures of a little chimney-sweep with the name 'C. Fox Westminster' on the front of his cap (by the Act of 1788 these boys had to wear their master's name on their cap), and of a pot-boy, with a string of pewter pots slung to his shoulder; he holds up a foaming pot towards Fox inscribed 'Jack Slang - Tree of Liberty Petty France'. The same inscription is indicated on his pots.
