Card Stunts created on a smaller scale (50 to 1,000 cards) are used as team building exercises for corporations, or to promote a new company logo, or recognize a company milestone. These card stunts, known as "billboard card stunts," are created using Coroplast cards that are held above the card holders heads. The largest billboard card stunt was created on September 17, 2013 in the desert outside Las Vegas by Kivett Productions. The card stunts were to promote the opening of Britney Spears new show at the Planet Hollywood casino.
