Merit Publishers, United States (cover designer: unknown, author: Che Guevara, introduction: George Lavan), "On Vietnam and World Revolution," 1967. Offset print, booklet

This English-language publication of Che Guevara's writings was issued by Merit Publishers in the United States around 1967, featuring his important essay "On Vietnam and World Revolution." The stark modernist cover design presents bold white text against black with a prominent orange-red rectangle containing the title—a striking visual representation of revolutionary messaging. The publication emerged during a period of intense speculation about Che Guevara's whereabouts, after he had disappeared from public view following his involvement in the Cuban Revolution. In October 1965, Fidel Castro had read a farewell letter from Che indicating his departure to support revolutionary efforts elsewhere, stating "Other nations of the world call for my modest efforts." The essay was originally sent by Che from "somewhere in the world" to the Executive Secretariat of the Organization of Solidarity of the Peoples of Africa, Asia and Latin America, and was first published by Prensa Latina before being translated into English and distributed by various international socialist publications. This Merit Publishers edition helped disseminate Che's revolutionary analysis to English-speaking audiences during the height of the Vietnam War, when his writings on international solidarity and anti-imperialist struggle resonated with activist movements worldwide.
