In 1919, Frenchman Eugène Christophe became the first rider to wear the race leader’s yellow jersey (maillot jaune) of the Tour de France.
In the first few years after the 1st world war, there was a shortage of material and dye for jerseys. So many of the teams wore the same grey colored tops: the cycle industry was not yet in action again, and La Sportive was the only marque supplying material was, and there was little difference between any of the jerseys they supplied.
