12. Kissing Coppers

Discovered on the wall of a pub in Brighton, England in 2004, Kissing Coppers depicts two male cops engaged in a passionate kiss. It is presumed to be Banksy’s commentary on gay rights and homophobia. In 2011, the pub owner sent the mural to the U.S. to be auctioned off.

13. Hitchhiker Anywhere

Found in Archway, London in 2005, Hitchhiker Anywhere was an image of Charles Manson trying to hitch a ride. It was tagged by a group of street artists called Team Robbo, in which they replaced “anywhere” with “going nowhere” using red paint. The authorities tried to restore the artwork by painting over the red paint and just leaving the sign blank. In an act of defiance and, possibly, to enforce their territory, Team Robbo painted white all over the whole artwork in 2011.
