My concern was with using a device to attach the handbill to a door- more precisely, using this particular device. The device is a lanyard. A lanyard is a cord used to hold something. Like a whistle. Or keys. Or a cellphone. It could have a 2 inch cord, dangerous enough to choke a chihuahua or have an 18" inch cord, enough to strangle a person. That is what I meant to inquire about...incorporating a item in my advertising campaign (an item known as a "Ad Specialty" or a "Premium" in advertising lingo), although it seems just the piece of cardstock that carries the advertising message could be dangerous enough. I would not be surprised that somewhere someone has been murdered or otherwise died unintentionally by paper cut.
