Casper & Nightmare #33

This Giant-Size Harvey Comics entry from 1971 pairs Casper the Friendly Ghost with Nightmare the Galloping Ghost in a cheerful Western-flavored cover scene — Casper rides atop a spectral white horse who's dipping his head into a trough, while a trio of bewildered cowboys react with wide-eyed alarm in a dusty frontier town. The left spine teases the book's generous lineup, spotlighting Spooky, Wendy, and the Ghostly Trio alongside the two stars, making this a packed 25-cent package of Harvey fun. With a story titled "The Red-Headed Sobbing Mystery" waiting inside, there's clearly no shortage of ghostly mischief on the range.
