How to avoid the horse duty [graphic]

"A stout farmer rides (left to right) past an inn on a cow. The cow befouls and tramples on a paper inscribed 'Tax on Ho[rses]'. The farmer looks triumphantly over his right shoulder at a group of spectators standing at the door of the inn, and snaps his fingers, saying, "Pitt be D------d". A basket containing poultry hangs from the saddle. Part of the inn is on the left of the design, its sign is a stout man holding a foaming tankard gazing at three sacks, inscribed 'Joe Jolly 1784' (a '7' appears to have been etched over the '4'). Five amused spectators stand by the door; from a window above two men applaud the farmer."--British Museum online catalogue
