Dr Manhattan in Vietnam (1970)
Above shows a front page article from The New York Gazette (dated: June 18 1970) - while the below photo shows Viet Cong troops bow down before Dr Manhattan in the process of surrendering (dated: June 21, 1970) - which perhaps might seem a tad insensitive, but hey, at least Dr Manhattan is wearing something to cover up his blue-glow-nasties innit? heh.
