The Mild Mild West depicts a teddy bear throwing a Molotov cocktail at three riot police. Banksy drew this mural in Bristol over three days in broad daylight in 1999. A specific trigger for the mural was such an event at Winterstoke Road, where riot police began to attack partygoers. In April 2009, the artwork was vandalized with red paint by an anti-graffiti organization called Appropriate Media, but was quickly repaired.

It was drawn in response to various unlicensed raves and parties held in abandoned warehouses around Bristol in the 1990s, that drew increased attention from the police. A specific trigger for the mural was such an event at Winterstoke Road, where riot police began to attack partygoers. The artwork is popular with the local community who consider it a good symbol of the heritage around Stokes Croft. It has been cited as an archetypal piece of Bristol culture, showing how a relaxed hippie can still fight back against the government and commercialization.

In 2009, after the artwork was vandalized with paint, Bristol City Council announced plans to enclose the mural in glass in front of new flats, which was criticized by the local community because it would make it harder to see from the street. Coexist, an organization managing regeneration of Stokes Croft, did not understand the vandalism. Their spokesman said, "I don't see how spraying red paint is helping with the positive change," and was happy that volunteers quickly came together to repair it.
