MONSTER MASHUPS #165

 This item from BIG SHOT #79 (1947) may qualify as the most obscure mm here. Two ghosts (named, unimaginatively, "Drakky" and "Franky") try to dodge their witch-girlfriends ("Haggie and Baggie"). The ghosts and witches change into human beings and bump into the long-forgotten star of the four-page strip, a teen schmuck named "Brass Knuckles."

Not only did the author like Frankie and Drakky enough to bring them back in BS 82, he has them introduce Brass to Horrible Horace, Bloody Boris and Gruesome Gertie.
