Superman #290

Superman strains against an invisible anti-gravity field, his fists colliding with a crackling barrier while people and objects — a tumbling woman, a man, a dog, and even a car — float helplessly in the air around him. The cover caption makes his frustration clear: he can't crack this anti-gravity field, and these people are doomed. Bob Oksner's cover sets up a genuinely tense premise for the featured story, "The Man Who Cried Super-Wolf!," with interior work by the reliable team of Curt Swan and Tex Blaisdell.
