‘Banksy’ sneezing woman artwork appears on Bristol house – BBC News

Banksy murals tend to poke fun at current affairs, so suggestions were made that the sneeze referred to Covid-19. One Totterdown woman added that it could be a nod towards the strong wind on Vale Street. Vale Street is known for being the steepest street in England and is home to an annual egg-rolling competition.
