The Clash sprayed punk graffiti and designed do-it-yourself punk shirts. With the cardboard stencil they refer to the guerrilla group Sandinistas, who overthrew a dictator in Nicaragua in 1979 - also with the help of political stencil graffiti. Banksy inspirer Robert del Naja started stencil graffiti partly because of The Clash: “I remember getting records from […] The Clash, they put stencils in their sleeves that you could use to paint on your clothes and all over the walls.”
