Neighbourhood Watch signs are designed to make a street feel safe. Their familiar lettering and friendly family portrait suggest that someone is looking out for the people who live there. Banksy keeps this instantly recognisable design but gives the uniformed figure at its centre the head of a pig.

The alteration is simple, yet it changes how the whole image reads. The smiling faces and warm colours still offer reassurance, while the pig introduces a pointed joke about policing and authority. Banksy leaves viewers to decide whether the figure is protecting the neighbourhood, watching over it too closely, or becoming the subject of suspicion himself.

By placing that question inside an everyday sign, Neighbourhood Watch shows how little Banksy needs to change an image to make its familiar message feel uncertain.
