Chas Gerretsen Chilean coup d'état. His famous photograph of General Pinochet became the embodiment of the Latin American Dictator, the opposite side of the political spectrum to Alberto Korda photograph of Che Gueverra (Guerrillero Heroico). The image of General Pinochet has an unusual history: it was used on posters, flyers and banners and was often reworked to portray the general as an inhuman monster. The first time Chas photographed General Pinochet, unwittingly, was on June 19, 1973 during the failed "Coup d'Etat", known as El Tancazo, which the general, ironically, helped put down. The images taken by Chas on 11 September 1973
