The image typically carved onto a Jack-o'-lantern is a scary or comical face. The most common design features a grinning or sinister face with triangular eyes, a nose, and a wide, toothy smile. These faces, often referred to as "jack-o'-lantern faces," are usually created by carving into the pumpkin's flesh and removing specific sections to form the desired features. Once the carving is complete, a candle or light source is placed inside the Jack-o'-lantern, creating an eerie glow that emanates through the facial cutouts. Jack-o'-lanterns are a popular symbol of Halloween and are prominently displayed as festive decorations during the holiday.
