Tussaud's Medium is a type of art form that involves the use of WAX to create sculptures. It was popularized by Madame Tussaud, a French artist who founded the famous WAX museum in London. WAX is used to create detailed and lifelike sculptures that can be used for a variety of purposes, such as creating historical figures or replicas of famous people. The WAX is heated and molded into the desired shape before being painted and finished with other materials.
