Halloween Postcard Showing Pumpkin-head Children Bobbing for Apples, 1910-1915

By 1900, articles in magazines and newspapers had helped spread and popularize Halloween customs and images like jack o-lanterns, black cats, witches, or bobbing for apples to a national audience. Some people marked the holiday by mailing a Halloween-themed postcard greeting to family or friends. During the first two decades of the 20th century, sending postcards was an easy--and popular--way to communicate.
