Seymour Chwast designed the protest poster "End Bad Breath" in 1968 to speak out against the unjust war in Vietnam. The poster used surreal imagery like Uncle Sam with airplanes bombing Vietnam emerging from his mouth to criticize American policy in a subtle yet impactful way. While the poster may not have changed many minds, it was an effective piece contributing to the larger anti-war movement by underscoring dissent and raising awareness about the government's flawed actions in Vietnam.
