Casper & Nightmare #16

This Harvey Giants issue pairs Casper the Friendly Ghost with Nightmare the Galloping Ghost for a cheerful supernatural showdown on the cover — Nightmare, the spectral white horse, rears up dramatically on a green hillside while Casper floats nearby, both seemingly startling a very real jockey and his brown racehorse. The left side of the cover teases the full roster of Harvey favorites inside, with small panels spotlighting Casper, Nightmare, Spooky, Wendy, and the Ghostly Trio. At 25 cents for Giant Size, 1967 readers were getting a generous helping of friendly frights with this co-starring team-up.
