Automobilia can be broken down into three major collecting categories—parts used for restoring cars, advertising and promotional items relating to a specific make or model of car, and decorative accessories in the shape of or with an image of an automobile. Numerous subcategories also exist. Spark plugs and license plates are two examples of automobilia with reference books, collectors clubs, and periodicals dealing specifically with these fields.
