This is a very simple item that never actually ended up getting any screen time in the film, but it's yet another great example of the little details the prop department thought about incorporating into the film. For the scene in which Koopa poses as a lawyer to interrogate Mario & Luigi, the prop guys made a cool little blue snakeskin business card holder along with some "Larry Lazard" business cards that Dennis Hopper would have had. This particular prop is not in the best of condition anymore and has become dry rotted over the years and is pretty brittle, but the 8 business cards inside are still in great shape!
