Unusually Psychedelic Vintage Anti Vietnam War era Pinback Buttons

Counter Culture Classics. A group of three unusually Psychedelic - in colors and design, vintage Anti Vietnam War era Pinback Buttons. Making them more interesting to me are the famous period anti-war slogans: "What if They Gave a War and Nobody Came", "War is Unhealthy for Children and All Living Things" and "When You've Seen One Atomic War You've Seen Them All".
