18. Crayola Shooter

Children in war is another favorite theme of Banksy. In this piece, a child can be seen holding a gun that is loaded with crayon bullets, addressing the loss of children’s innocence as they get involved in war and terrorism. This piece was stenciled on the wall of an Urban Outfitters store in Los Angeles.

19. Cardinal Sin

The Cardinal Sin structure, which was unmasked at the Walker Art Gallery in Liverpool in 2011, featured an 18th century bust of a cardinal with a pixelated face. It was an allegory on the controversial issue of sexual abuse in the Catholic Church.
