In 1393 King Richard II compelled landlords to erect signs outside their premises. The legislation stated "Whosoever shall brew ale in the town with intention of selling it must hang out a sign, otherwise he shall forfeit his ale." This was to make alehouses easily visible to passing inspectors, borough ale tasters, who would decide the quality of the ale they provided. William Shakespeare's father, John Shakespeare, was one such inspector.

Q: In what year did the king demand ale-sellers post signage on pain of forfeiture?
