Casper & Nightmare #20

This Giant-Size Harvey Comics pairing brings together two of their most beloved ghostly stars in one 25-cent package — Casper the Friendly Ghost gleefully riding atop Nightmare the Galloping Ghost, while a terrified centaur flees in a panic below them. Warren Kremer's cover art captures the duo's playful chemistry perfectly, with Nightmare's spectral white form soaring alongside a vivid red centaur scrambling across a hillside. The sidebar previews promise even more Harvey fun, spotlighting Spooky, Wendy, and the Ghostly Trio — making this 1968 issue a wonderfully packed treat for fans of the whole Harvey universe.
