The Superman Family #174

This January 1975 Giant-sized DC anthology puts Supergirl front and center, and Kurt Schaffenberger's cover delivers the stakes immediately: the Maid of Might streaks across a city street, her cape already scorched and blazing where a massive winged serpent's eye-beams have found their mark, while panicked bystanders scatter below. The tagline — "Supergirl Faces Peril from the Eyes of the Serpent!" — tells you everything you need to know about the tension on offer, and the creature looming overhead looks more than capable of delivering it. Rounding out this giant package are additional features spotlighting Jimmy Olsen and Lois Lane, making it a satisfying read across the whole Superman Family.
