Vintage Halloween Greeting Card with Clown/Witch Figure & Pumpkin

Why is a figure in a green polka-dotted clown costume having what appears to be a full psychological crisis while being aggressively nuzzled by a grinning jack-o'-lantern head wearing a jaunty blue bow — which, for the record, does not make the jack-o'-lantern look less threatening? The pumpkin, equipped with flowing blue ribbons and a smug three-toothed grin, has apparently decided that draping itself over the clown's shoulder is a completely normal social interaction. Meanwhile, the clown clutches what appears to be a tiny doll — because apparently the ideal festive Halloween greeting features a figure-within-a-figure situation that immediately raises questions about recursion and existential dread. 'Wishing You and Yours a Happy Hallowe'en' reads the text, cheerfully, as if none of this is happening.
