Vintage Halloween Greeting Card with Ghost & Jack-o'-Lanterns

With their mouths agape in what the card's artist optimistically called 'surprise' but what modern psychologists would classify as 'trauma,' two children in matching dark outfits clutch their jack-o'-lanterns with the grim determination of tiny Victorian debt collectors, while directly behind them a full-sheet ghost lurks against a tree, presumably waiting for the perfect moment to ruin everyone's evening. A witch on a broomstick cruises past a full moon overhead, presumably late to a meeting. The children have clearly spotted the ghost, and if you wanted to convey 'Halloween Greetings,' apparently two small children being actively haunted in a forest at night is the preferred method.
