Published: William Holland. Political satire: Pitt is the coachman driving the 'Union Fly' with Fox and another politician in harness over a road littered in boulders marked 'Subsidies', 'Income Tax', 'War of Extermination' etc.; John Bull and his wife ride on the roof, lamenting the bumps and not getting a place inside, it being full of the coahman's friends; another man falls by the wayside with bundles of 'Pickings' for himself and his family. Description from the British Museum.
