This CGC 7.5 copy of Detective Comics #293 (July 1961) features Batman and Robin in “Prisoners of the Dark World!” — a science‑fiction adventure with vivid alien designs and dynamic action. Art by Sheldon Moldoff, Nick Cardy, Joe Certa, and Charles Paris captures the colorful imagination of early 1960s DC storytelling. With white pages and strong color contrast, this mid‑grade example is a perfect addition for collectors of Silver Age Batman and sci‑fi crossover issues.
