This is a vintage Halloween postcard illustration. It depicts a comical scene with a woman in a red dress and white apron reacting in shock to a cow with jack-o'-lanterns for a head. The woman is shown with a surprised expression, hands raised, and is in the process of dropping a bucket. She is wearing a bonnet and appears to be running away from the cow. The cow is standing behind a wooden fence, with two carved pumpkins placed over its head, giving it a spooky appearance. A cornstalk and a crescent moon are visible in the background, along with a small house and a bare tree. The scene is set on a patch of green grass. Below the fence, the text reads, "What the boys did to the cow."
