SHOULDN'T IT BE...
JUST KIDDING...
Bibendum, commonly referred to as the Michelin Man, is the symbol of the Michelin tire company. Introduced at the Lyon Exhibition of 1894 where the Michelin brothers had a stand, Bibendum is one of the world's oldest trademarks.
Since 1912, tires have taken on a black appearance because carbon is added as a preservative and strengthener to the base rubber material. Before then, tires took on a gray-white or light, translucent beige colour. This helps explain why Bibendum is white, though modern tires are black.
