Rock

A true Silver Age rarity from Charlton Comics, Rock made his debut in 1957 alongside a wonderfully offbeat cast that includes Rollo, Li'l Tomboy, Li'l Genius, Cimota Mouse, and Ollie Orwell — a quirky ensemble that gives you a real flavor of Charlton's charming, anything-goes spirit of the era. Turning up in both Rock and Rollo and Li'l Tomboy, this character may have a modest three appearances in the catalog, but that scarcity is exactly what makes him a fascinating footnote for collectors who love hunting the overlooked corners of late-1950s comics history.
