Sgt. Fury #52

This 1968 Marvel issue tackles some of World War II's darkest territory head-on, with the cover — penciled by Dick Ayers and inked by John Severin — depicting the Howling Commandos dressed in prisoner-of-war stripes behind barbed wire, overseen by an armed German guard, while a defiant figure kneels in the foreground, fists clenched. A cover blurb confirms that Happy Sam Sawyer is among those imprisoned alongside the Howlers, raising the stakes considerably. "Triumph at Treblinka!" promises one of the more sobering and dramatic chapters in Sgt. Fury's wartime saga.
