Classic T-Shirt, worn at Rock Against Racism and even featured during the Rude Boy movie. 'Brigade Rosse' is Italian for Red Army, and RAF stands for Red Army Faction. Strummer worre the shirt to raise awareness of their existance, as opposed to actually support their cause, as although he himself was a so *** t, he condemned the Brigade Rosse as a terrorist group.
Although in the picture above the shirt appears in bad quality, I myself have ordered and received a copy of it and let me assure you that it is far from sub-standard quality.
