Warren Publishings venerable titles Creepy, Eerie and Vampirella all got their starts in the Swinging Sixties, but they continued to please throughout the Disco Decade of the Seventies, too. The 1979 Eerie Yearbook (regular issue #106) collected four mid-60's tales by writer Jim Stenstrum, and artists Richard Corben & Jose Ortiz that featured the amoral, freelance contract killer Hard John Apple; under the title "Hard John's Nuclear Hit Parade".
Set within a post-apocalyptic world following two religious wars that have virtually wiped out humanity, left the planet deserted and left the survivors struggling in a dog-eat-dog world, Eerie #106 presented an all-too common genre theme from those years, with one man trying to make a difference in a world that had already died aborning. I haven't had the issue in many years, but it made a a good impression on me at the time and I seem to remember Hard John going out with a real bang at the end - - - and taking the last remaining army (Russian/?) with him.
