A door hanger is a printed piece, usually rectangular in shape, that is made with a die-cut hole or hook that allows it to be suspended from a doorknob or handle. Most of the door hangers are promotional in nature and printed with colorful graphics on one or both sides of durable cardstock. They are often used by businesses to promote their products or services in a specific neighborhood or area. These flyers typically include information about the business, special promotions, contact details, and a call to action to encourage the recipient to engage with the business in some way.
