Vintage Halloween Greeting Card with Jack-o-Lantern & Children

The black cat has a distinctly purple eye, which surveys the scene with the quiet dignity of someone who has witnessed something best left undescribed. What we're looking at is essentially a well-dressed boy in a flat cap clutching a stick and announcing his intent to commit pumpkin-based violence against a child in a ghost sheet who is, frankly, asking for it—crouching aggressively while brandishing a grinning jack-o-lantern on a stick like some kind of deranged carnival barker. The caption 'OH, I'LL WALLOP THIS ONE' confirms what the boy's body language already telegraphed: this isn't a greeting card, it's a police report waiting to happen, dressed up in sepia tones and signed by the artist like they're proud of it.
