Action Comics #277

This June 1961 issue of Action Comics packs in a delightfully unusual scene: Superman and Supergirl soar side by side, each cheering on their respective super-pet as Streaky the Super-Cat and Krypto the Super-Dog engage in a mid-air tug-of-war with a heavy chain — with a city skyline visible far below. The cover, penciled by Curt Swan and inked by Stan Kaye, captures the playful rivalry perfectly, with both cousins of steel animated and clearly invested in crowning the "Super-Pet Champion." Inside, writer Jerry Siegel and artist Jim Mooney deliver the main story, "The Conquest of Superman!", alongside the promised extra feature spotlighting Superman's mightiest feats — making this a genuinely packed ten-cent package.
