LBJ is a surreal documentary by Santiago Alvarez which mixes photo montage with footage of Lyndon B Johnson's background and political life. With moments of Monty Python style animation and crude juxtaposition the film attempts satire and humor while portraying LBJ as a merchant of death. The poster is a classic using the same style of photomontage, objectifying and ridiculing. Reboiro also worked on the film's imagery and is credited in the titles.
