Instructions
Try movie theatres. Talk to a supervisor about what the theatre will do with their large cutouts after the movie is not running. You may be able to make a deal for purchasing one of the figures you see sitting in the lobby.
Try supermarkets and retail stores where life-sized cutouts are on display. Talking to a manager may get you a direct sale of a model cutout. You may have to wait until the advertising campaign is over.
Try party supply stores. These celebration clearing houses sometimes offer attractive life-sized cutouts of diverse characters. PartyBox is one party retailer that sells life-sized cardboard figures.
